I use freebsd6.1
the server sometimes becomes crash about twice in a month.
According to freebsd handbook I did kernel debug.
I enabled dumpdev in rc.conf
after the crash made vmcore.1 file.
I typed "kgdb kernel.debug /var/crash/vmcore.1"
I read as below
Dumping 511 MB (2 chunks)

Doesn't ram of the server work properly ?
Do I have to change this ram ?
Thanks
