no local heartbeat?..

[Horvath Andras]

Hi, 

I'm new to this list so hello to you all. :-)

I use heartbeat for a 2-node cluster, connected via 2 serial and 1
dedicated ethernet links. All seems to work well, except that I
recently got this into the logfile (and heartbeat died, the other node
took the services):

Feb  2 16:45:52 bingyom heartbeat[22722]: WARN: node bingyom: is dead
Feb  2 16:45:54 bingyom heartbeat[22722]: ERROR: No local heartbeat.
Forcing shutdown.
Feb  2 16:45:55 bingyom heartbeat[22720]: info: Heartbeat shutdown in
progress.

When does a node pronounce _itself_ dead?
The machine works well, running for weeks now, w/ kernel 2.2.18pre23,
heartbeat 0.4.8-1.
When I restart heartbeat, it takes over its own resources and all is
back to normal..

I suppose it must be me :), but how?

thanks
