Issue



After upgrading to 7.5 through 7.5.0.3, multiple bpdbm processes appear to be using excessive CPU time.  The number of bpdbm processes will build until it eventually interrupts the regular operations of NetBackup, triggering various application faults.


Error



When this occurs, various processes may fault:

Wed Jun 20 2012 12:22:34 Application Error E1000 Faulting application HPWbemDump.exe, version 1.0.1.0, faulting module msvcr80.dll, version 8.0.50727.6195, fault address 0x0000000000006a68.
Wed Jun 20 2012 10:34:44 Application Error I1004 Reporting queued error: faulting application bpdbm.exe, version 7.500.312.605, faulting module msvcr100.dll, version 10.0.40219.1, fault address 0x00000000000761c9.

Following one of the hung bpdbm pids, the log will show the following:
