Greetings -<br>
<br>
For the past few weeks my Mailscanner duo has been slowing down. I have a pair of SLES10 boxes running Postfix and MailScanner v4.62.9. I realize this is a slightly old version, but it had been running very well for a long time.<br>
<br>
Last night I began digging around and discovered the MailScanner children are dying very quickly (just a few minutes), and replaced with new siblings. If I understand MailScanner's architecture, the children should live for 12 hours before being replaced by the master?<br>
<br>
This morning I have upgraded one MailScanner node to the latest STABLE version (v4.70.7), but the problem still remains.<br>
<br>
I thought the issue may have to do with MailWatch, so I disabled the "Always Looked Up Last" function. This change had no effect.<br>
<br>
At this point it appears some messages are being scanned multiple times by different children, which slows the process down dramatically. Thinking this was a locking issue, I changed Lock Type to posix, also with no effect.<br>
<br>
The speed reported in syslog seems decent for most batches:<br>

This box is running as a VM session, but on very decent hardware with 1GB ram.<br>
<br>
Any thoughts on where I should investigate next?<br>

Thank you for your assistance and ideas.<br>
