Since some days, we experience issues with long timeouts when browsing on the osticket frontend (1-2minutes). together with the timeouts, the ticket counts disappears from the menu. top level ticket count is disabled.

during that, the server runs 100% CPU on all cores for the "SELECT COUNT(DISTINCT..." queries which we think count the tickets in each queue. sometimes multiple of these queries run parallel and run from 45 to 200 seconds.

after a lot of try and error with figuring out which search criteria in which queue might cause these issues, we found out that it is probably caused by fields from custom forms.
When there is a custom form involved a LEFT JOIN to ost_form_entry_values is added to the count query like this:
LEFT JOIN ost_form_entry_values B2 ON (B1.id = B2.entry_id)
As long as there is only one of those the query runs fine in < 1s.
We couldn't figure out when exactly but sometimes a new queue or a new criteria in a queue adds the same LEFT JOIN again and just names it differently until we end up with something like this:
LEFT JOIN ost_form_entry_values B2 ON ( B1.id = B2.entry_id)
LEFT JOIN ost_form_entry_values B3 ON ( B1.id = B3.entry_id)
LEFT JOIN ost_form_entry_values B4 ON ( B1.id = B4.entry_id)

With 2 of those the query runs for about 3s and with 3 it starts to become unusable with about 120s. If we manually remove those additional joins and rename the referenced fields the query again runs in under 1s.

As a reference I attached full queries with the slow one running over 120s and the "fast" one 3s. I wasn't allowed to upload text files, so PDF it is 🙂

CentOs 7
osticket version: 1.12.2
php 7.3.10
MariaDb 10.3.18

Probably similar issue as here: https://forum.osticket.com/d/95235-slow-staff-login-after-adding-ticket-queue

    yes. we have still the same behaviour
    **
    **

    Out of curiosity how many tickets do you have?
    and
    When you say "the server runs 100% CPU on all cores" how many cores and what speed are they?

    I have the exact same issue...

    I dont think we have a lot of tickets. its this many
    But I have over 75 agents logged in and its killing OSticket. Same issue....its taking multiple seconds to open a ticket and view its details.

    Also if I make a search, i invariably end up with an "internal server error" message. This was all great with OSticket 1.10, we upgraded from 1.10 to 1.12 then to 1.14 ....love the addition of new features in 1.14 but the slowness is killing me

    I've noticed that its very slow when many agents are logged in. Right now I have over 35 agents logged in and the queries are down to a crawl it seems. Any tips/suggestions please?

    35 doesnt seem like a a lot of agents for MySQL queries at all

    @DA7276727

    Check your server resource usage and provide more resources where needed. You might need a better/more CPUs or more RAM.

    We are looking into how we can improve count query performance but until then, you'll just need to make your server handle the load.

    Cheers.

    Thanks Kevin, so this is expected behavior?
    is it the number of concurrent users or the ticket count that I need to curtail while we wait for you to do optimizations.
    I'll give it more resources nonetheless....

    Thanks for your response

    I think recently I post very similar problem on this forum or on github
    Check my post and if you found this, check if this is related to your case.

    how to modify the code for disabling the count of the queue?
    this is killing osticket, I have a lot of ticket and I lot of queues

    What mLipok is saying is that you do not need to edit the code to achieve this. Simply go to:
    Admin panel -> Settings -> Tickets
    Locate Top-Level Ticket Counts
    uncheck it.
    Click Save Changes

    @riccardo_centropaghe

    You should look at converting all MyISAM tables to InnoDB and removing keywords from all the queues (even personal queues for all agents). Once you do this they should be fast again.

    Cheers.

    Hello boys,
    Same problem here, it happened to me several times without realizing that the problem had to do with the queues. I tried several hosts and I have reinstalled osticket several times. unfortunately the queues are one of the last things that one configures since in general the help topics and their forms are generated first.
    I was very frustrated, because every time I had the system ready to go into production I found that the database stopped working, and the response times became terrible. in fact, every time this problem happened I lost access to the database either via phpmyadmin or via dbeaver. even after deleting the osticket files the query kept looping. Two different hosts blocked my service because the problem was generating a very high response time throughout the server. I have not found a solution yet, but I can confirm that the increase in response time has a direct relationship with the queues. now i'm scared to add queues with custom form fields. It's a shame because it is a super useful tool, and I would encourage you to say necessary to use. hopefully they can identify the problem and find a solution.

    thanks for this thread, it helped me not to feel alone and understand that the problem has nothing to do with a personal failure to implement the system, but a problem that affects us all.

    I would like to know how it is that in the self-hosted version that you can hire, you do not experience these problems, and if so, how do you deal with them?

    For those with the same problem, I recommend making a backup of the database before adding every new queue, in order to identify which is the custom field that generates the problem and avoid it. this way you can restore the last working state without losing big ammount of information. unfortunately when this problem happens in general the database stops responding and the cpu usage skyrockets until the instance or service is restarted, or the sql queries are stopped manually, which I cannot manage in general in the standard hosting with cpanel.

    Another tip is to have a test database to make the queues without putting the production system at risk, so that if it fails, it will do so in the test environment, and if it works we will know that it is safe to replicate in the environment. productive.

    I insist it is not a problem of server hardware capacity, since I tried with several hosting and also with cloud services such as aws and the problem was the same regardless of the hardware. it is a loop of death that knocks down even the most powerful server until the cycle is cut.

    I also take the opportunity to tell you that I also experience the fairly common problem that the ticket count throws me ghost numbers, that is, it throws me a number that does not correspond to the result it shows when I select the indicated queue. I consider that both problems must be related.

    @fnixt

    I do not agree. While the queues and counts can be optimized a little better, the problem is the host’s hardware and services. A good example can be found in a recent thread where the OP was having slowness when loading queues. He was using Debian 11 and when he switched o Debian 10 he has no issues at all with the same config and everything. Another example is a customer was having super slowness on the queues, so we converted the tables to InnoDB, upgraded to MySQL 8, boosted the server specs, made a few MySQL config optimizations and the issue was resolved. The common factor in all the cases comes down to the host machine.

    You can improve slightly on the code side by editing the following file:

    You need to remove/comment out the try part and just leave the catch like:

    //        try {
//            $counts = array_merge($counts, $query->values()->one());
//        }  catch (Exception $ex) {
            foreach ($queues as $q)
                $counts['q'.$q->getId()] = $q->getTotal();
//        }

      il try the code mod and come back to comment.
      anyway i cant find a clear way to convert to InnoDB, searched the forum finded some threads but, cant realize it.
      if you know about some step by step to realize it i will appreciate it a lot.

      as allways, thanks a lot KevinTheJedi you are great and your labor is taking the food to ours mouths.

      sorry about my english it's 1am and im not using translator.

        Something else, the db admin gived me this query as the one wich gives the problem (i restored the failing DB and tryed to login and the loop comed back again). they finded this manually and gived me this:
