We ran into the same problem with SP3. After turning OTM off, BPCD abended
the server.  The group we get our support through found a reference on
Novels sight to problems with the TSA500 NLM that shipped with SP3 abending
the server when using Backup Exec (see link below).  The recommended
solution was to downrev the TSA500 NLM to the version that shipped with
SP2.  We did that and where able to backup the server.  We have not turned
OTM back on yet, so I do not now if that fixed the problem of OTM abending
the server.

Subject: [Veritas-bu] Netware CLient 5.1 w/SP4

Is anyone using Netbackup with Netware 5.1 client and SP4 yet ? I want
to go to SP4 and bypass SP3 due to many problems I have seen with it,
but on the server I upgraded to SP4, I have problems.
After NBU client is loaded, it is impossible to unload bpcd. I type
unload bpcd at the command prompt and it doesn't unload.
Everytime I try to run a backup, OTM abends the server almost
immediately.
Veritas support didn't have a copy of SP4 until I called to open an
incident with them, they are downloading it now, but may not be able to
support it.
Evironment is Netbackup 3.4.1 on a Solaris 8 server, Stek 9740
enclosure w/8 DLT7000 drives, mixed NW5.1 SP2, and NT/2000 clients.
Any input ?
Thanks in advance.
