Hi. I have an amd64/3.7-stable machine here running apache with mod_ssl and php 5.0.4. SSLMutex is set to 'sem', the default. Intermittently the httpds start segfaulting. Of course the parent process remains, and respawns them. There's a large number of clients and the machine is kept pretty busy.
The httpds always end the same way: 26510 httpd CALL semop(0x70000,0x7f7ffffeced0,0x1) 26510 httpd RET semop -1 errno 13 Permission denied 26510 httpd CALL semop(0x70000,0x7f7ffffeced0,0x1) 26510 httpd RET semop -1 errno 13 Permission denied 26510 httpd CALL semop(0x70000,0x7f7ffffeced0,0x1) 26510 httpd RET semop -1 errno 13 Permission denied 26510 httpd PSIG SIGSEGV SIG_DFL code 1 addr=0x2f2e2e trapno=6 >From what I've read, semume and semaem values that are too low can cause this. I've cranked semume to 100 but haven't messed with semaem since that's actually hardcoded in sys/sem.h. Should I be messing with semaem or is there something else at work here? I'm tempted to try a file mutex but saw a post (which I only vaguely remember) where henning@ said it was defaulted to 'sem' for permissions reasons and that file wouldn't work right. I'm at my wits end with this... anyone have a solution? Thanks much in advance.
