Thanks for the clue !

I think I found the problem, i have this sometimes in the apache logs :
[15981] EACCELERATOR: PHP crashed on opline 37 of file() at xxxxxxx:66

I have the segfault a few lines later and a nfs_getpages + vm_fault in
/var/log/messages at the same time !

It seems like a bug in php or eaccelerator when accessing a file when it
is edited by another server...
