Title: LLT errors - delayed and lost hb ticks

you have two LLT streams sharing common infrastructure/switch/VLAN.

Each LLT link must be completely independent and neither stream should see packets from the other.

Hi all,

We are running VCS 4.1 on a two Solaris 9 systems and have configured a local cluster for our Configuration Management software called Clearcase. Recently I have been receiving a lot of the following LLT latency errors:

Does anyone know what exactly is causing these delayed and lost ticks and how they can be corrected?

Thanks,

Winston Kawaley
