The master server appears to "freeze."
The condition described in this document can be seen when ALL of the following conditions have been met:
- NetBackup Java/non-Java administration console hangs when selecting Storage Units, Lifecycle Policies, etc.
- Command line execution of nbemmcmd and bpstulist commands (for example) hang indefinitely without reporting output
- Restarting the NetBackup Enterprise Media Manager (nbemm) service does not help.
- Sybase SQLAnywhere has NOT run out of cache per server.log
The root cause is multifaceted:
- NetBackup nbdb database/query issue
- NetBackup environment and/or configuration resulting in heavy load
- Possibly underpowered/underprovisioned master server hardware
