reiser4: fd -1 problem ?

["Artur Makówka" <juice@ursynow.2a.pl>]

Hello, i've been investigating this problem for few weeks, and it seems 
reiser4 can be reason for this.

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)
