Description
The EFSM Test Generator that is run at EfsmTestGeneratorVhdlTestCase hangs on b11 VHDL design (or this testcase continues more than 8 hours - it is very suspicious).
The log fragment is attached below.

- Priority changed from High to Urgent
The test still hangs on Hudson.

Now this testcase produces at Hudson server the java.lang.OutOfMemoryError with the following error log:

Possibly testcase prints too much to stdout. You need either to forward the stream to file or to shrink the logging.

What is the target maximum heap size?
Updated by Sergey Smolov about 9 years ago
I can't find related Hudson settings. You may try to remove all the engine output except the most wanted information. After that I'll check it on Hudson (see e-mail).

By the way, why not to use Retrascope logging subsystem for engine output's filtering?

How much RAM is on the Hudson server?

I'm using it.

I've shortened the INFO output. Maybe it's enough.

But it is not. Can you mark all the engine output as "DEBUG" (except, for example, the resulting coverage)? In fact this output log is still exhaustive and huge.
By the way, you may reproduce this bug on your PC by applying the following patch to build.xml:

Done. The test target from build.xml has passed EfstTestGeneratorTestCase successfully.
But I see your commit. Should I discard my changes?

I've just changed the loglevel for some INFO-messages to DEBUG level. Also I've checked it on my PC. The testing on Hudson is in progress.
I think you'd better to merge your changes with mine before committing.
