Locked Weird freeze up with v2.5 and Signalink USB #signalink

Mark, WD4ELG

Windows 10 build 19044, patched and up to date
X64 AMD 8 core processor, 3.5 years old, 16 GB of RAM

Sometimes the behavior happens 2 or 3 times a day, other times I can go a week with no occurrences.

Running six instances of WSJT-X: two using SignLink, three using installed sound cards in the rigs (IC7300 x 2, IC 705), and one using KiwiSDR audio.

The observed behavior is that WSJT-X stops decoding for one or both of the SignaLink devices. The waterfall is frozen. There is a signal showing on the control panel as coming through, but nothing gets decoded. I have to kill and relaunch the WSJT-X instances to recover.

This never occurs with the ICOM 7300 rigs or the IC-705 rig. It never happens with the KiwiSDR RX signal either.

I have tried everything I can think of (power, USB standby options, etc.) but I can’t find the root cause.

Any suggestions appreciated. Thanks.
