How much do you pay for that support contract? If you are paying anything
at all, I suggest that you withhold any payments, until they have helped
you with this issue, or sent you a fix.
The error you get is one that happens in the client API. By default
many client API has a command timeout of 30 seconds, which means that
if no data has come back in this time, the client gives up waiting.
There are two possible reasons why this timeout elapses:
1) Blocking.
2) The query takes a long time to run.
Judging from the output you posted, there is no blocking. (The DB
lock you mentioned is perfectly normal. All processes take out a lock
on their current database.)
On the other hand, process 65 appears to be busy. It has a lot of CPU
time accumulated, and I don't like UNKNOWN TOKEN. That's usually a
sign of something performing less well.
So call the vendor again, and be more insistent that they help you
to sort this out. At very least, they should change their app, so
that it sets the command timeout 0, which means wait forever. Then
at least, you would get a result, even if it would take some time.
