ASIP File Server getting "hung/frozen/etc.", but other services work...

Seems to be related to "OT Auto Push Support" extension in your system folder. This extension is used for the TCP Filtering, but note that TCP filtering does not actually have to be in use, just the presence of that extension is enough to cause problems.

1. Remove the "OT Auto Push Support" extension from the system folder
2. Restart your server
3. This will totally disable TCP filtering which is a bummer.
4. Maybe try Doorstop Server Edition from Open Door Networks for a better TCP filter?
