Hello,
This is really nasty, but a nice find-- apparently the same problem occurs
in 7.5.0.1 as well, thank you for posting!

Subject: RE: [Veritas-bu] NetBackup 7.5.0.1 restores fail when restoring
large numbers of files?
I've noticed this in the 7.5 operational notes:
If you attempt to restore a large number of files such as 2,000,000, the
restore
job may remain in the queue state in the NetBackup Administration Console.
If that happens, you cannot restore those files.
This issue is the result of the bprd process, which uses almost 100% of the
CPUutilization and a significant amount of memory. These two things
together,
causes the restore job to remain in the queued state
We're debating on whether to go to 7.5.0.1 or 7.1.0.4.
Sounds like this issue would be cause us problems in our DR tests...
I was leaning toward 7.5.x, but now may tilt toward 7.1.0.4...

Hi,
We've done a number of restores of 10-50M+ files, this last test was only
around 1-1.2 million files, went back to 7.1 in the meantime. I have the
images that caused the issue so I'm duping that from tape to disk and then
will re-import to the test-environment and dup back to tape if necessary and
try to reproduce in the test environment.
Justin.

How much data? How many files? I'm testing 7.5.0.1 in my test lab right now.
So far I haven't seen any issues for my environment, but I haven't tried any
"large" (more than a few dozen files) restores yet.
