Email fetching doesn't seem to be working after upgrade to 1.17.3

For some reason it appears that my email fetching has stopped working since updating to 1.17.3. The cron job runs fine, but no emails are pulled from the mailbox (Office 365 using oAuth2). Has anyone else seen this? Any ideas?

Found that I am getting the following error in the log:

[27-Apr-2023 10:46:03 UTC] PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 12570680 bytes) in /home/cccbr/public_html/osTicket/include/laminas-mail/src/Protocol/Imap.php on line 208

Though I have got the memory limit set to 512M in php.ini

The IMAP connection is timing out as in taking too long. How many emails are you fetching at a time? What’s the fetch frequency? I would suggest lowering the limit and expanding the frequency a little to see if that improves. If not then you can try testing the IMAP connection to see what could be going on.

Cheers.

Problem solved - worked out that some emails with really large attachments were clogging things up - moved them out of the way and all working again now. Thanks.
