Hi All,
I've been tuning a server recently and just today this has started to
appear in my top/htop output.
[root@db1 ~]# ps -aux | grep kernel
root 1011 0.0 0.0 212048 4532 ? Ss 13:34 0:00 /usr/bin/abrt-watch-log -F

I had made a few changes to sysctl.conf which I have now reverted and
the error still exists.
my sysctl.conf contained;
vm.swappiness=0
vm.overcommit_memory=2
vm.overcommit_ratio=90 - this was only added this morning because of an
'out of memory' error in postgresql.
kernel.shmmax=35433480192
kernel.shmall=2214592512
which I have now removed.
Can anyone shine any light on this? A little search on Google mentions
faulty memory, I will install memtest today and see what the output is like.
Thanks
Michael
