Thread:Project:Support desk/Problems after upgrading to 1.22/reply (4)

I have only seen it when viewing Special:SpecialPages. I cannot rule out the possibility that it also happens on other pages but I haven't seen it. When I first upgraded to 1.22.0 it would fail on Special:SpecialPages every time. After a few hours it started working properly, then it failed consistently for several hours, then it started working again. Now it works more often than it fails and when it does fail it usually starts working again on the second or third attempt to view Special:SpecialPages.

I'm not ruling anything out but I would be surprised if it is my version of PHP. It is a supported version and hasn't given a problem before. At one point I thought it my be due to APC but disabling that had no effect.

I note that some other people have reported problems immediately after upgrading but the issues have gone away (or the poster has stopped responding!) without any fix being applied. I don't know if the problem I'm seeing is a symptom of the same issue or something different. If it is something I've done I'd like to fix it! If it is a problem in 1.22.0 I'd like to help debug it, so happy to provide any information that would help to get to the bottom of this.
