Hi , I have a server that acting as a mail router - mean a lot of messages to deal with . The machine running freebsd FreeBSD 6.2-RELEASE with SMP support and postfix to handle the mail . Today I had a system crash due to kernel panic (see the kgdb output below) I saw some discussion regarding this issue in the freebsd forum but I don't think this is the same problem . http://www.freebsdforums.org/forums/showthread.php?t=45114 dose any of you had any idea what the problem might be and how can I fix that ? Thanks in advance Ram The kgdb output : [GDB will not be able to debug user-mode threads: /usr/lib/libthread_db.so: Undefined symbol "ps_pglobal_lookup"] GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
