Anybody any ideas what this might be? No one on the Gentoo fora could work it out. The weird thing is that sometimes after a graceful restart, the problem goes away.TIA Link to comment https://forums.phpfreaks.com/topic/35087-error-attaching-to-shared-memory/ Share on other sites More sharing options...
steviewdr Posted January 23, 2007 Share Posted January 23, 2007 Did you run a memtest?Would it be possible to disable mod_ssl for a while to debug and test? or did the problem only occur when you updated to PHP5?-steve Link to comment https://forums.phpfreaks.com/topic/35087-error-attaching-to-shared-memory/#findComment-167142 Share on other sites More sharing options...

I am not sure when the problem started but it certainly worked when I first set up apache.

binro Posted January 24, 2007 Author Share Posted January 24, 2007 Someone emailed me the solution. Stop Apache and delete all the files in /tmp owned by apache. That did it, no more segfaults. :) Link to comment https://forums.phpfreaks.com/topic/35087-error-attaching-to-shared-memory/#findComment-168370 Share on other sites More sharing options...
