Are you sure you posted the last Simconnect log, the one generated immediately after the Pushback went stuck ? I'm asking, because according to your Couatl.LOG, this session did not disconnect, so it seems to come from a normal session with no issues, and no exception report, as in your first log.
According to your Simconnect log, there were two exceptions, both caused by RAAS Pro:
> 7.34362 [127, 1]Open: Version=0x00000002 Name="RAAS Professional"
< 208.61085 [127] >>>>> EXCEPTION=3, SendID=26, Index=-1 <<<<<
< 238.56244 [127] >>>>> EXCEPTION=3, SendID=30, Index=-1 <<<<<
127 was the ID number assigned to that module for this section, so you can use that ID to find who generated the Simconnect error. But still, it doesn't seem this session had the same problem your reported in your previous report.
