For the past several days I've been migrating our ticket system from osTicket ver 9 to ver 18.
In the test environment everything seems to perform well. Yesterday we got our first legitimate customer on ver 18 production deployment.
Tonight while closing the ticket ( maybe during and I only noticed after) I received an email from the system with the following IO error.
As far as I can surmise this has not impacted the client or the osTicket system in any obvious way.
But being a long time user of osTicket I know this is a red flag.
Can anyone tell me what this error means, and suggest possible solutions?
Thanks for your time and attention in the matter.
