Re: Newbie: Mozilla and Firefox windows "disappear" under FC3 2.6.11

Hi Clive,

I saw your email in the Fedora archive and wasn't sure if you had received 
a reply.

I ran into the same problem with my new database server and it would crash 
anytime under load.  I did some searches and found a workaround by 
executing the following command:

echo 0 > /proc/sys/kernel/randomize_va_space 

This basically turns off the virtual memory space randomizer that is a 
feature of the 2.6 kernel.

The server's been running fine under the same high load conditions for a 
day now.

BTW, the posts about this problem seem to be centered around AMD Opteron 
cpus.  If you're running on Intel, this might not fix it, but it's worth a 
try.

Good luck,
Tony
