[news.eclipse.tools.emf] [CDO] Timeout while getting worker Thread?!

[Stefan Winkler <stefan.winkler-et@xxxxxxxxxxxxxxx>]

Hi,

as some of you may already know, I am doing quite large calculations
which end up producing a lot of objects.

E.g., I have a calculation, which creates a resource with about
1,500,000 new CDO objects each of which have bidirectional references
to several existing CDO objects. Thus I get very large transactions.

I'm currently running into a weird timeout error which I don't really
know what to do about:

ERROR] java.util.concurrent.TimeoutException: Worker thread activation
timed out after 10000 millis

What could cause this timeout? Are there too few Worker Threads in the
pool? But then again, the pool should grow, shouldn't it? 

Any ideas?

Cheers,
Stefan
