Random segfaults are usually memory (RAM) problems. Run memtest (it should
be an option on your installation media boot). When stuff runs OK for a
while and then starts failing, it could be a overheated CPU (bad fan, etc).

> Thanks for your response. I acted on this. I ran memtest but it returned no errors. I was using two memory modules from two different  vendors. I removed on 256M module. Now I have single 512M module and memtested this one also. I monitored operating remprature and system load and they are perfectly normal. I also disabled swap to rule out any corruption in swap. Things have improved but I still  get segfaults and application crashes ( frequeny of fauliures is very low now) Is there is anything else I can do to improve the state of my system. My system is not overclocked (one user has suggested that also).
