Hi All,

we are running Corosync 1.2.0-0ubuntu1 on Ubuntu 10.4 beta w/current
updates; the cluster consists of two systems running in KVM, each on a
dedicated host.

We have observed several times, but are unfortunately unable to nail
the exact cause, that when the virtualised system that is running
corosync has a "hiccup", i.e. hangs for couple of seconds when we
introduce a delay into its storage access, then the corosync process
enters an endless loop from which it doesn't ever seem to recover.

In this endless loop the process uses 193% CPU in the 2-CPU
virtualised system, and is issuing a stream of wait4() system-calls
(with an occasional nanosleep() and some futex-stuff).

...?

Thanks, Colin
