I keep having programs die with signal 10 and 11 errors. The two main
victims are the X server and the compiler.
This is really annoying since the kernel is getting quite stable now but
I can't leave long compiles while I go and do something else because
it could stop at any moment and every few hours or so my X server will
die.
Someone else reported a while back that their X server was dying from
sig 10 and 11 errors as well. One of the XFree86 people suggested
possibly a corrupted xerver or a server bug. I've checked my server
isn't corrupted and it's ok but I suspect that there's a general bug
somewhere that's affecting large memory users since cc suffers from
the same problem (and also make sometimes).
Once a program has died in this fashion it won't restart until I've
rebooted the machine, then it will work fine for a while before dying
again. This suggests that it's not a problem with any particular
program since they work fine for a while and the fact that they won't
restart suggests that the problem lies elsewhere.
I've tried logging out and back in again, just in case it was a
dodgy shell causing problems, but that doesn't work. I have to do a
reboot. Since it's sig 10 and 11 that's always reported then my first
thought was that there's something going wrong with the use of
memory by user processes. Is this likeley.
Does anyone have any idea what's happening?? Since I'm sure there's
a bug lurking here somewhere I'd appreciate any info that would help
track it down.
Also, I remember someone mentioning why the compiler sometimes dies
with sig 6 errors. I can't find that post could can someone tell me
again please.
Thanks.
