Re: Synchronet 3.21e upgrade

Hey folks. I recently updated Synchronet to 3.21e on my machine by downloading the sbup321e.zip and extracting the contents over my existing install.
There's an upgrade_to_SBBS_v3.21e.exe in that zip, I assume you ran it?
I had been running 3.19 prior. My host VM is a Windows 10 32bit
environment and the prior version had been running just fine for a while. Every since the upgrade I am having some pretty major stability problems. The first thing I noticed is that in the Synchronet Control Panel GUI the Terminal Server Buttons and text which state Running NT Service flash every couple of seconds. Additionally. if I attempt to stop the service the "sbbsNTsvcs.exe" hangs and I have to manually kill it. Also, after a a day or so the service stops accepting any kind of inbound connections.
Not a lot of sysops use sbbsNTsvcs.exe, so first question would: do you have problems if you disable the NT services and just run sbbs.exe or sbbsctrl.exe directly? In the mean while, I'll do some more testing with sbbsNTsvcs.exe and sbbsctrl.exe together to see what I can find.
Anyone else running Synchronet v3.21e as NT services?
I'm not really seeing any errors in the rror log related to the connections, but I do see that the system appears to have stopped polling netmail and QWK. I tried to manually force a QWK callout but I am seeing this in the log:

I'm really hoping someone can lend me a hand to figure out what is going on.
It sounds like the event thread is hung runing a QWKnet call-out event. How many hubs do you have setup in SCFG->Networks->QWK and what are their call-out command-lines? That doesn't explain the not answering incoming connections though.
