The following error is logged to the aveksaServer.log file ($AVEKSA_HOME/wildfly/standalone/log/aveksaServer.log):
  
2020-01-16 10:14:18,216 [Worker_alertq#Role#jdbc/avdb_6] ERROR com.workpoint.queue.work.AlertQWorker - 
Exception caught during alert evaluation. 
Alert 'DependencyCheckToCompleteWorkItem', AlertID=76:WPDS, JobID=4760:WPDS, ProcessRef='WF_FF_17', 
WorkItem=55970:WPDS:1, FIFO=19787464 (offset=836646ms)
Exception was: java.lang.OutOfMemoryError: Java heap space
java.lang.OutOfMemoryError: Java heap space

You allocate more memory to java, finish the upgrade and restart RSA Identity Governance & Lifecycle but the problem remains.

Please refer to RSA Knowledge Base Article 000030327 -- Artifacts to gather in RSA Identity Governance & Lifecycle to find the location of the aveksaServer.log file for your specific deployment if you are on a WildFly cluster or a non-WildFly platform.
 
Cause
The significant error in this case is:
 
java.lang.OutOfMemoryError: Java heap space

Running out of memory can cause unpredictable behavior. In this case, running out of space caused the workflows to be inaccessible.
 
Resolution
The resolution to this issue depends on the symptom(s) encountered when running out of Java heap space. See the Workraround section in this RSA Knowledge Base Article for possible solutions.
 
Workaround
In this case redeploying the workflow architect ear file and restarting RSA Identity Governance & Lifecycle solved the issue. 
  1. Determine if the workflow architect ear file is currently deployed:
$AVEKSA_HOME/wildfly/bin/jboss-cli.sh -c --controller="127.0.0.1:9999" --command="deployment-info"
If the RSA Identity Governance & Lifecycle workflow architect ear file is deployed, it needs to be undeployed. If the ear file is already undeployed, skip to step 4 if standalone and step 5 if clustered.
  1. Undeploy the workflow architect ear file (Standalone)
$AVEKSA_HOME/wildfly/bin/jboss-cli.sh -c --controller="127.0.0.1:9999" --command="undeploy aveksaWFArchitect.ear"
  1. Undeploy the workflow architect ear file (Cluster)
$AVEKSA_HOME/wildfly/bin/jboss-cli.sh -c --controller="127.0.0.1:9999" --command="undeploy aveksaWFArchitect.ear 
--server-groups=img-server-group"
  1. Deploy the workflow ear file (Standalone).
$AVEKSA_HOME/wildfly/bin/jboss-cli.sh -c --controller="127.0.0.1:9999" 
--command="deploy $AVEKSA_HOME/Aveksa_<patch-directory>/aveksaWFArchitect.ear"
  1. Deploy the workflow ear file (Cluster)
$AVEKSA_HOME/wildfly/bin/jboss-cli.sh -c --controller="127.0.0.1:9999" 
--command="deploy $AVEKSA_HOME/Aveksa_<patch-directory>/aveksaWFArchitect.ear --server-groups=img-server-group"
  1. Restart RSA Identity Governance & Lifecycle
acm restart
If this does not resolve your issue, please contact RSA Identity Governance & Lifecycle Support for further assistance.
