Re: [Veritas-bu] Network Connection time out (41)

Just a couple shots in the dark. Could the issue be network congestion? Many older firewalls can't keep up with the data transfer and start doing bad things to packets. How about traffic shaping? Nothing like low priority backup traffic to ruin your day. And as always - patches, nic drivers etc?

Subject: [Veritas-bu] Network Connection time out (41)

Hey guys

I am receiving a Network Connection time out (41) on a consistent basis when I run a backup on two of our servers. The servers are behind a DMZ but I have set the BPCD connect-back to use the VNETD port and it worked for a long time but now all I receive are 41 errors. The servers do write some data but eventually error out. I am able to telnet to port 13724 on both servers so there is no blocking on the firewall for that port. Any assistance would be appreciated.
