Hi,

Yes. In case when the server crashes both UDP and TCP ports are down.
Please note that monitoring only on UDP with TCP removed from the config
file results in correct ldirectord behavior i.e. the entry is removed
after crash of the machine. Also restarting the ldirectord assures that
UDP entry for crashed host is not present anymore. The point is that
once a real server is placed in the routing list for UDP and UDP is
combined with TCP on the same port than UDP entry is never removed from
the list. TCP alone and UDP alone both result in correct behavior.

Best regards,
Andrzej.

Horms would be better to answer this than me. In case he doesn't pop up
straight away...

is the UDP test for a dead UDP port, working and sending the correct
signals to ldirectord?
