NetBackup primary container goes into unhealthy state

It may happen that the NetBackup primary container goes into unhealthy state on its own and the following error message gets displayed:

bashrpc error: code = 2 desc = oci runtime error: exec failed: 
container_linux.go:235: starting container process caused "process_linux.go:110: 
decoding init error from pipe caused \"read parent: connection reset by peer\""

This also causes the ongoing backup and restore jobs to fail. (APPSOL-148171)

Workaround:

Stop the NetBackup primary container (nb_master) forcefully and wait for few minutes till the master container starts on its own.

# docker stop nb_master
