This happens when all SMTP-workers are busy in system calls (virus scanner, pfd, office, zip extraction..... - waiting for DB answers, and some others). While such tasks are running, the workers can't be interrupted by the MainThread. If this happens after the rebuild is finished, a possible solution would be to restart assp after the rebuild.

Hi all, I hope everyone's healthy and being safe. I've been getting a warning like: Mar-25-20 08:20:12 Warning: Main_Thread is unable to transfer connection to any worker - try again! periodically for a while now. It comes in waves, with the warning appearing every 60 (almost exactly) minutes for a couple hours, then it seems to go away. It doesn't seem to start happening mid-day, I've only seen the warnings start after the overnight a rebuild completes. Nothing's changed configuration wise, loads are about the same as usual. Restarting ASSP always makes the warnings subside for a couple of days. The SMTP conections gui recommends 5 workers, I have 6 set. Often, but not always, the log shows "Saving config" about 40 seconds before the unable to transfer. Everywhere I looked, I see this with a 40 second or so pause in the logs, I don't know if there's no activity or if it's hung. It's a windows server with MySQL. Lots of ram, ASSP using about 1.8gb (grows over time), MySQL about 2gb. Are those normal numbers? Any suggestions on what I can look into to see what's making Assp hang? Thanks, be smart and safe out there!
