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.
