Hey Paul,
    If the systems were fine, the slowed down after a restart.  I could
be that infamous Full/Half duplex mismatch between the NICs and Switch
ports & never permit any server to use "Autodetect".  I've been burned
many a day autodetect and Cisco strongly advises against using
autodetect in a datacenter.  Just my 2 cents.

Subject: [Veritas-bu] broken pipe messages in bpdbm logs,and system
slowdowns


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.
