Hi,
BBOUT is basically an error file. How about removing the errors that
cause the messages?
What kind of messages do you see in BBOUT?
A "/bin/mv /home/bb/BBOUT /home/bb/BBOUT.old" in crontab is better than
"cat /dev/null > BBOUT".
You will then allways have some error messages left, in case you would
need them.
You could start by moving the file once a month.
If you move the file at the same time that some process has it opened
for writing, then "fun things" might happen: The process continues to
write to the same inode (disk area) that now has the name BBOUT.old. If,
on the other hand, you choose to "rm BBOUT" then the file name is
removed from the directory structure, but if some process has the file
(inode) open for writing during that rm, you will end up in a situation
where the file is not visible anywhere, but the process is unaware of
that and continues to write to the inode. This ghost file consumes disk
space and continues to grow as usual... I'm sure that any trouble will
be gone by next reboot, though. This happens on the vxfs file system.
Might also be true in other file systems, so beware. Having some process
write data to disk without creating a visible file feels real bad
(especially if you are the sysadmin). So avoid deleting files that are
opened for writing. Moving is safer. Shutting down bb (and ALL its child
processes) prior to working with BBOUT is even more safe.

Subject: {bb} BBOUT extremely large on bb16e1
Hi,
I noticed that even for the clients that bb is monitoring, the BBOUT
in
bb/bb16e1 is extremely large. Is it advisable to cat /dev/null > BBOUT
the file or is there some other way to minimise the hard disk usage of
BB as the partition that bb is installed on is rather small.
regards, Josh
