We have 2 OpenVMS 2-node clusters where we've seen one cluster member lose all its routes. Both clusters have been using dynamic routing in listen-only mode. When we do UCX SHOW ROUTING on the affect node, all we see are a route for the loopback interface and the local subnet. Meanwhile, the other cluster member still has all the routes. We do have UCX supporting the cluster alias, if that's relevant. One system manager escalated the problem to the CSC and was told "we advise customers to disable routing in UCX". While we can install static routes, using dynamic routing means we don't have maintenance if routers come & go (and each system is on a LAN with multiple routers). One system is UCX V4.0 on OpenVMS V6.2, the other is UCX V4.1 on OpenVMS V6.1. Known problem? Any suggestions for fixing?

Known problem! This is a UCX V4.0 bug, whereby UCX$INET_ROUTED runs out of event flags, and never comes out of hibernation; the problem is fixed in ECO2, but you may as well grab the latest patch, ECO#5 from LASSIE::UCX$PATCH: Meanwhile, a quick ucx> stop routing and ucx> start routing should get all your entries back into your routing table. /Dave - Sydney CSC | |||||
