Connection refused: Child 16061failed to establishumbilical to moderator!
Hello Theo!

Thanks for your quick response.

Yes - i know. I also wondering why only Node B is Crashing. There are
several other applications running on this Node
(also on the other 3 Nodes) like MySQL, Sendmail, Proftpd... and so on. So i
think it shouldn't be a Memory Failure or
such thing.

The only differnt is, that on Node B also some sites are using mod_perl
(Node A & Node B make a failover
Cluster, so like my description, Node B could also provide both
Backhand-Groups - but in the moment there is no
failover situation - all is running fine). I will try this Config-Option and
will tell you if it solves my problem!

Thanks!

Andreas
