Anyone seen anything like this before?
Not much info on veritas support.
 
19:01:34.635 [23522] <2> put_string: cannot write data to network:
Broken pipe (32)
19:01:34.639 [23522] <2> db_senddata: put_string(): connection dropped
or not connected, Broken pipe, (32)

I came across these while investigating a system slow down from a couple
weeks ago.
Our full data center was shutting down for maintainance, adn the weekly
fulls were replaced by INC, and started early Friday aft.
around 7pm, all the running jobs dropped to less than 100KB/s per job.
my co-woprker, who was on call, rebooted everything....jobs restarted
but same speeds.
some jobs didn't finish, but everything had to be shutdown at
midnight...when everything was brought back up on Sunday, backups have
run fine since, so I supspect a problem external to the backup system,
though other groupd are pointing the finger, as the problem was only
visable via backups.
;o)
 
oh, back to the errors, I came across the error messages as I was
searching through logs, though I soon discovered they have been in all
the logs for weeks, though they do not correlate with any job failures,
so there are no apparant symptoms of these messages.
