Hehe. Very strange. Following a recent kernel update, the apache segfaults (and often associated glibc errors) I've been seeing have been vanquished.
Unfortunately they've been replaced by:
[notice] child pid 9708 exit signal Bus error (7)
Before anyone suggests it, the system's memory is 100% fine and coincidentally has been recently tested along with all other main hardware components (and in any case is ECC). This is more likely indicating a lack of memory for apache to use somehow, even though the VPS in question has 2Gb allocated to it and normally uses less than 1Gb of that, or is just a different manifestation of the original bug/oddity.
So although the words have changed, the music is still the same
Anyway, the reason for my posting is just to warn people to look out for this as well as for segfaults if you run a Virtuozzo or OpenVZ-based system.
