Re-occurring Issue with Process-Exec Engine Going Into Fatal State

Hello,

We are currently facing a repetitive issue with the Appian engines: At least once a week, different unexpected behavior occur in the application without returning any alert. We run the checkengine.bat and we observe each time that Process-Exec00 is in Fatal. We typically stop the Appian engines (stop-suite.bat), copy the last good .kdb file and rename it to the latest file name+1 in folder and everything looks again good for a couple of days. However, this is not a desired behavior and this becomes frustrating to do every couple of days. Please find attached the Appian logs for the latest event. Could you please help us figure out what is the cause of this repetitive issues?

Thanks in advance,
Octavian
