Since 2 or 3 weeks we have problem with amavisd-new on postfix. We got 
several lines like this :
(!)_DIE: Suicide in child_init_hook: BDB no dbS: Lock table is out of 
available locker entries, . at (eval 51) line 30.\n

And we must restart amavisd because our spools keep on growing and 
growing in deferral queue. We had to disabled bekeleydb with amavisd. We 
have found segfaults in /var/log/messages too. We tried Marc Martinec's 
solution described in this thread 
http://sourceforge.net/mailarchive/message.php?msg_id=47B333C4.8050204%40phnet.fi
Unfortunately it doesn't seem to work. When we look closer to log files 
it seems that our message pass amavisd check and an error is fired when 
message is reinjected into postfix (see my log file below). We use 
centos 4.6 with amavisd-new 2.5.3 and postfix 2.4.6.

with 127.0.0.1[127.0.0.1] while sending end of data -- message may be 
sent more than once)

I would understand why there is a difference between size of message 
declared and actual message size and what could we do against that ?
I think BerkeleyDB lock's problem is a consequence of amavisd's crash. 
Is it to possible for example to tell amavisd that this kind of message 
should be deleted or forced with the good size ?

Thanks in advance for your answer.
