After standard maintenance restart of vApp, JBoss has both *.dodeploy and *.deployed files and it is preventing the web application servers from starting.
Release : 14.3, 14.4
Component : IdentityMinder(Identity Manager) Virtual Appliance
In /opt/CA/wildfly-idm/standalone/log/wildfly-console.log shows information like this:
"Server VM warning: Failed to reserve shared memory."
After a routine restart of the VM, JVM applications were unable to start.
Two versions of files *.deployed and *.dodeploy existed.
Due to file permissions hotfix to delete extra .dodeploy files was provided.
Further issues related to memory were observed.
The issue was caused by the change in memory provided to the machine by Virtualization software (it was reverted to the default amount).
vApp was restored to previous memory values.
The system started and works fine now.
