Fw: MailScanner 4.67.6 - Double processing of message and then Unlink error

Sat Mar 8 00:34:44 GMT 2008

I have been having double processing of a message and then an unlinking
error from the second child.  Since my server has very very low volume I
 just set the children to 1.

 Basically the problem, as I see it, is that while Child 1 is processing the
message, Child 2 starts processing.  After Child 1 has decided what to do
with the message and removes the message from mqueue.in, then Child 2 has
finished deciding what to do and then can not find the message to take
action.  I think this is close the "duplicate message" problems, but since
my volume is minimal, Child 1 can remove the message before Child 2 takes
action.

 I upgraded to 4.67.6 and set children to 5 and have the same problem.

 -----------------------------------------

 Even SpamAssassin realizes it is the same message and indicates "cache hit"

I think the issue is the following phrase when MailScanner is starting:

"Creating hardcoded struct_flock subroutine for linux (Linux-type)"

 Details
 MailScanner 4.67.6
 OS is equivalent to RHEL3 - Whitebox EL3
 Sendmail 8.12.11

 What other information can I provide?
 Any suggestions?

 Thanks,
 Steve
