Dovecot Logging and Shell Script Hang

Greetings,

We have a PHP based shell script that runs a doveadm backup routine.

This script was running just fine, and then we turned on more logging for Dovecot (enabled the mail_log plugin). For some reason, once this was done, the shell script would run for a few minutes and then hang, as it added more log messages to the dsync STDOUT. Once the mail_log plugin was disabled, it ran without hanging.

Is there any way to run doveadm and temporarily suspend the mail_log plugin? Or is there a better way to do this?

Thanks for the insights. Asai
