sporadic error new QSO

[dk4rh]

I am quite often do FT8-QSOs by using wsjt-z
Since months I have the sporadic issue, that access errors are popping up and swisslog is not logging any more. Have to restart Swisslog.
For other reasons I have change the configuration a little bit and found out:

In wsjt-z and Swisslog I had activated QRZ for searching the callsign in the Internet database. (I have the subscription there).
After changing in Swisslog to HAMQTH not one of this errors came up. Is now running without those errors for 3 days.

Seems this is happened if two programs are searching for the callsign. But wsjt-z has not this problem, is still running without such or equal erros.

Maybe this info is helpful to find the root cause?

Attached a view error popups from last year.
