We are lucky to have a new (to us) faster server donated since this
original May posting on the "unable to transfer connection to any worker"
error.  However, with the new box with Windows 2019 installation, fully
patched, MySQL latest community, and Strawberry perl 5.32 it's still
happening in spurts.    Not a heavy load, 16gb ram.  12 cores total.  ASSP
uses about 1.7gb after running for a bit.  MySQL seems fast, ClamAV in use.

Sometimes I get the warning just once in a day, often it's every *5 minutes*
for a while.  This morning, there were 3 occurrences with 10 minutes in
between each.  But always, when I look at the log, it's right after the
"Saving config" process, always when there's no config changes.

I tried to see where SaveConfig() is being called from every 5 minutes.  I
>>think<< it's when the ReloadOptionFiles timer hits, but I'm not sure.
ReloadOptionFiles is set to 300 (5 minutes)
AutoReloadCfg is enabled, though I'm never modifying assp.cfg without using
the GUI
What else should I be looking at?


>From today:

Oct-25-21 11:09:24 Saving config

save - file d:/assp/assp.cfg is unchanged

assp acts normally for 10 minutes, then:
