Explanation: nbjm returns this error whenever a protocol error occurs with an external process that tries to communicate with nbjm. External processes include bptm, tpreq, bplabel, dqts, vmphyinv, or nbpem.
Ensure that the NetBackup software on the master and the media server is from an official NetBackup release.
If the problem persists, submit a report with the following items.
Unified logging files on the NetBackup server for nbpem (originator ID 116), nbjm (117), nbrb (118), and PBX (103). All unified logging is written to /usr/openv/logs (UNIX and Linux) or install_path\NetBackup\logs (Windows).
Legacy logs are in subdirectories under /usr/openv/netbackup/logs/ (UNIX and Linux) or install_path\Netbackup\logs\ (Windows). If the directories do not exist, create directories for each of these processes and rerun the job.
Contents of /usr/openv/db/jobs/trylogs (UNIX and Linux) or install_path\NetBackup\db\jobs\trylogs (Windows).
bpdbjobs output: run bpdbjobs to obtain the state and status of all jobs.
