sshd and crond dead when scp large file


Hi there,

I am quite new to linux and today I found something strange.
One of the linux server I managed seems unable to handle large file copy. I once tried to copy 4Gig file using SCP from my other linux server (let's say I copy a 4Gig file from server A to server B), but suddenly sshd crond and perhaps other daemons on server B are down.

I can copy large files from server B to server A with no problem tho.

Where can I find logs to diagnose the problem?
What might cause sshd and other daemons sudden death?

Thanks before
Regards,
Arie

1. check relevant logfiles on B after a crash
2. run 'top' on B before/during a copy; see if anything pops up
3. could be lack of temp space on B. If multiple daemons are dying, could be lack of space on partition containing log dirs eg /var
4. what are distros/versions/32 v 64 bit on A & B ?
