My apache process is from no clear reason suddenly peaking to 95% CPU usage and it stays that way until i kill it and start again. It happens 6-7 times a day, i have hosting services on my server. I thought it was apache fault, but it strings shows this: [pid 31610] munmap(0xb6f29000, 729088) = 0 [pid 31610] mmap2(NULL, 729088, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb6f29000 [pid 31610] munmap(0xb6f29000, 729088) = 0 [pid 31610] mmap2(NULL, 729088, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb6f29000 in endless loop, when this strange 'lock' happens. is it a problem of fd -1 ? of course that could be also apache bug, that it can't handle wrong fd number, but why there is wrong fd number? i ran reiser4.fsck and it didnt help. i use kernel 2.6.12.6 with latest 2.6.12 reiser4 patch, as it seemed the most stable from recent releases. What could be the problem here, and how can i repair it ? should i keep running fsck.reiser4 until it finds it ? it doesnt happen very often, but like i said 6-7 times a day, but it varies, sometimes it more often sometimes almost 0. thanks in advance for response. (this is probably not Apache issue, i already asked for this many many times)
