I upgraded from 3.8.0 to 3.8.1 and added graphviz support in the wee hours of last night. All seemed fine. I was able to graph ticket relationships and I worked until about lunch before I encountered a problem where each webpage is blank. I am definitely connecting to the web server, but nothing is displayed. I have "Out of memory! Callback called exit." Errors in my apache2 logs. My system is Debian running in a vm with about 700mb of ram available and I have about 2000 tickets.
I found the following information (below) which seems to pertain to my situation. My question is (and no offense to Sebastien as I really appreciate his posting this solution), but is this the appropriate action to take? Do I simply need more RAM or is this an error with the schema? I am reticent to go making changes that will come back to haunt me later. Thus far in an attempt to resolve the problem I have only restarted apache2 and the server. Neither made any difference. Thank you, Joshua Re: Problem after an upgrade to 3.8.1 Remove Highlighting [In reply to] Hello David, The problem looks like the session table is being corrupted. I modified the schema using: ALTER TABLE sessions CHANGE a_session a_session LONGBLOB; Now everything seems to be working fine. By the way, I am also using a virtual machine. 256Mo were enough for 3.8.0. I increased the available memory to 512Mo but this did not solved the problem. I hope this trick will solve your problem.
