crash dump server for red hat ent 4

Is it true that you can't have the crash dump server/client on the same server?

I know I've installed Nagios open source before, I though it's only for that kind of thing. I never though that Red hat ent 4 would be like client/server on the crash dump.

if someone is having problem with high file descriptor and your kernel logs doesn't have much or no error at all, the only way the red hat support could analyze your problem is through crash dump and above is the only way. or if you are having problem with your applications and your kernel couldn't tell.

any comments will be highly appreciated?
