How big a kernel dump can be on 32GB m/c.

[hari krishnan <p.harikrishnan22@xxxxxxxxx>]

Hi kernelnewbies,

I have a system which has 16GB memory +16GB for swap space total space required in /var/crash is 32GB.
Can I keep less then 32GB for /var/crash ?  many times I see kernel dump less then 20GB.

My problem is we have 32GB RAM memory in production machine on RHEL5U5 and I don't have 64GB space for /var/crash.
Could anyone tell me what is the minimum /var/crash we should have to get dump stored.

Thanks,
Hari
