BPEL Database Adapter "Faulted while invoking operation.." --where to look?

Question

Hi,
I hope that someone can assist me. Occassionally in production a database adapter step will fault. On the BPEL Console flow diagram for the step I can see "Faulted while invoking operation XXXXX on provider YYYYY". The step retries, but the fault never appears to resolve.
The database being accessed is available and I am able to perform the same query manually. Only a reboot appears to solve the problem.
Where do I look to see the cause of this fault? I have looked in the following log but cannot see anything either related to the adapter, flow or flow id. Should I look anywhere else?
Thanks - Anit

Hi,
Below is what the database adapt step shows in the flow diagram. The flow contains several other database adapter accesses prior to this, to the same database, and these completed correctly. I will look in the log file you suggested.
Faulted while invoking operation "DB_ID_PETICION_MNP" on provider "DB_ID_PETICION_MNP".

...same as before. This repeated 4 times.
Finally rebooted the server, and the adapter completed OK:
