[Info-ingres] Ingstart fails with CLFE05_BS_CONNECT_ERR Unable to make outgoing connection.

[Steve]

We have a HPUX 11.11 Server running Ingres 2.6 and 
we've recently installed Ingres 10s as part of our upgrade prep. 
So we have 2 instances of Ingres on the box.

The problem we have is that the 10s installation won't start, 
it bails early on, at the point of starting the recovery server:

So at the point of failure, the name server has started and the recovery server is in the process of starting,
maybe at the point of registering itself with the name server(?)
It is actually an _intermittent_ problem, it has started successfully a few times, when it works, this is what we see next in errlog.log

E_SC051D_LOAD_CONFIG  Finished loading configuration parameters for configuration '(DMFRCP)' of server type 'RECOVERY'.


The installation is left with just the name server running, connecting to it gives the same E_CLFE05 error seen in the errlog.log...

ingres II $ iinamu
E_CLFE05_BS_CONNECT_ERR Unable to make outgoing connection.


Any suggestions?
How can we localise this further?

TIA
