After deploying two times simultaneously from Android Studio by mistake, I had a "409 Conflict Another transaction by user XYZ is already in progress for app". I undid the transaction using appcfg rollback, as suggested:
Beginning interaction for module default...
0% Rolling back the update.
Success.
Cleaning up temporary files for module default...
The problem is that now any attempt to deploy the module does not pass 99%. The log is as follows:
95% Will check again in 1 seconds.
98% Will check again in 2 seconds.
99% Will check again in 4 seconds.
99% Will check again in 8 seconds.
99% Will check again in 16 seconds.
99% Will check again in 32 seconds.
99% Will check again in 60 seconds.
99% Will check again in 60 seconds.
99% Will check again in 60 seconds.
...
Thank you!
