I just want to add that one of the main benefits of the Forums 
(http://forums.4d.com) is that it is also used by the 4D Engineers and they do 
monitor, read, and participate in the discussions. So posting on the forums 
could give you the opportunity to discuss this directly with the Engineers. 
This participation is one of the main reasons why Feature Requests are handled 
on the forums (as described here: http://kb.4d.com/assetid=76725).

I wish it were that simple. I see some theories about what's causing it but I 
don’t think anyone has nailed down a concrete explanation or reproducible test 
that could be used in a bug report. Sorry, but I cannot file a bug report for 
something this vague. Although, to be clear, I have tried running some tests to 
see if I can provoke the issue and I never saw it (so technically if a bug was 
filed with the information we currently have it could be marked as 'verified 
and non-reproducible' by tech support).

It is great to see confirmation that using the Runtime Explorer allows the DB 
Admin to issue the command RESUME PROCESS; this gives me hope that we are on 
the right track and for the time being we have a way of kicking the process 
back into gear. I will continue monitoring this thread for additional clues but 
at this time I still don't have enough information to reproduce the issue and 
ultimately file a bug report.

For anyone following along and actively looking for this problem, hopefully you 
are also using the Information Component to log reports on a regular basis 
(default 5 minute interval) so that if the issue does arise you have a set of 
reports that depict the period of uptime for the database. There may be a clue 
in these reports (for example, an item in the attention section warning you of 
an issue). At the very least the reports would include the amount of uptime for 
the computer, which could be used to help understand at which point of uptime 
this problem is happening (assuming it is related to uptime).

-Tim
