Process model kicks off, but no instances created [1]

Hello all,

OS: Sun Solaris
IS: 6.1
Relevant Fixes: WmPRT_6-1_SP2_Fix9, IS_6-1_SP2_Audit_Fix3, IS_6-1_SP2_Core_Fix8, Monitor_6-1-5_Fix16

The problem I am facing is mighty close to the one stated here:

except that we are already using a database for audit store. When the appropriate document is published, the process model kicks off - I can tell by the entries written to server log by the services corresponding to the steps of the model, yet, the instance does not show up in the monitor.

The design, generation and testing of the model is in the same environment - no migration from Windows or anything.

Any ideas guys?

Thanks, R
