Revision 16 posted to Appian Knowledge Base by Viet Nguyen on 2/27/2020 8:54:14 PM

Symptoms

On an on-premise environment, Appian Engines fail to start following a hotfix deployment or version upgrade due to transaction replay error with the following message in the service_manager.log:

ERROR com.appian.komodo.translog.OutstandingRequestsTracker - Outstanding write requests was decremented again after the all writes logged event.

Cause

This is due to a bad Service Manager version on the following Appian build versions:

19.4.76.0 to 19.4.89.0
19.3.130.0 to 19.3.141.0
19.2.196.0 to 19.2.208.0

To verify your build version, please check the build.info file located in your <APPIAN_HOME>/conf/ directory.

Workaround

Please open a support case with Appian Support to receive the fix for this issue and follow the instructions below to apply the fix:

Download and unzip the komodo-1.236.0.zip file provided by Appian Support to any directory that is not <APPIAN_HOME>.
Shutdown all components of Appian gracefully
Rename <APPIAN_HOME>/services/bin to <APPIAN_HOME>/services/bin_backup

From the unzipped komodo-1.236.0.zip file, copy the ‘bin’ directory into <APPIAN_HOME>/services
From the unzipped komodo-1.236.0.zip file, copy the ‘lib’ directory into <APPIAN_HOME>/services
Start Service Manager, ZooKeeper, and Kafka on all engine nodes using <APPIAN_HOME>/services/start.bat|sh -p PASSWORD -s all
Stop Service Manager, ZooKeeper and Kafka on all engine nodes using <APPIAN_HOME>/services/stop.bat|sh -p PASSWORD -s all
Start Appian normally using the steps provided in our Starting and Stopping Appian documentation

Once your environment is running with the patch successfully applied, your environment should once again be in a stable state.

Please proceed to perform cleanup by:

Removing <APPIAN_HOME>/services/bin_backup
Removing <APPIAN_HOME>/services/lib_backup
