[Samba] PANIC in logs. What does it mean? How to avoid?

[Peter Volkov Alexandrovich]

Hello.

Now  have samba-3.0.7 installed on my system. The problem is this strange 
message in my logs:

Nov  9 14:36:18 alustem smbd[14188]:

 [2004/11/09 14:36:18, 0] lib/util.c:smb_panic2(1381)
   PANIC: PANIC: deferred_open_entries_identical: logic error.
 [2004/11/09 14:36:18, 0] lib/util.c:smb_panic2(1389)
   BACKTRACE: 1 stack frames:
   #0 /usr/sbin/smbd(smb_panic2+0xfc) [0x81bb594]

How should I debug this problem? Is this problem serious.

Please help me. This is in production enviroment, so it need to be up forever. 
I'm very worring about this.

Thank you in advance,

Peter.
