Обсуждение: gborg's apache server ...
At first, I thought it was just a 'fluke' that it was crashing ... but I just restarted it, and sent it a manual SIGHUP, and it crashes right off ... I've tried SIGHUP'ng other VMs on that same server, running the same template, and all of them do as expected (kill all child processes and restart) ... I've added a cron job runnig every 60 minutes to 'start' the daemon, so that when the log rotate happens to happen next, at least it won't stay down ... but, can anyone here think of a "configuration" reason why it might be doing this? There is nothing in the log files to indicate a problem, other then that persistent SegFault ... Anyone with any thoughts? ---- Marc G.

Yeah - look at it from another viewpoint - what has changed in the last few days on that VM? Have you upgraded anything in the template or the VM itself? Probably the only other ppl (except any staff you currently have of course) who could have done anything like that would be me or Chris, and I know I haven't touched it. Regards, Dave
I have not changed anything either. Jan is the only other person I know who has access to the server. Is he on this list?

That's not the problem - we have admins, we're just trying to ascertain if any of us made any changes that might have upset apache. /D

I don't think its anything we've changed ... I wish there was a better way of tracing what caused the SegFault ... I can recreate it on other VMs if I enable the interbase.so extension, but that is already disabled on gborg ... Got it .. thanks to gdb, it turns out the issue was the pspell.so extension ... commented it out, and it no longer dies on a SIGHUP ... will keep an eye out for the SegFaults over today ... ---- Marc G.

Why can't we just disable EVERYTHING we are not using? I mean why in the world was the interbase module at any point loaded on Gborg? Sincerely, Joshua D. Drake > > ---- > Marc G.
