Hi,
I experienced lots of kernel panic after I installed openwebmail on my
mail server.
The environment is :
[Mail Server] <=> [Mail Spool Server]
nfs
Mail Server: 6.1-RELEASE (panic 3 times a day)
Mail Spool Server: 6.0-RELEASE
I also installed www/apache20, mail/postfix.
The mount options is rw, quota (Yes, I used quota)
I have tried to replace my kernel, but GENERIC and custom kernels panic, too.
Please give me some advice :)
