GBE and netbackup

Hi all,

I have a quite strange problem. We are using gigabit etherenet for backup to the Veritas NetBackup Server. It was running fine for a whlie but after sometimes it gave us
"(40) network connection broken" error.

I testusing the ftp using this GBE link (big files) it was ok. There is no error mesages on /var/adm/messages or syslog.dated. The funny thing if I run the the netbackup through the fast-ethernet, everything is OK.

What was wrong? Is it the GBE network? but the other backup using this network running fine. Is it some parammeter need to be changed?
or is it the Netbackup?

notes: the nebackup is 3.4 and the unix is Tru64 4.0 F running TruCluster 1.6

Regards,

Iwan

Re: GBE and netbackup

Lower the packet size (ifconfig mtu), disable path discovery (inet: pmtu_enabled=0). Maybe this will solve timing issues.

Please provide:
# netstat -i
# netstat -m

Help() { FirstReadManual(urgently); Go_to_it;; }
