Description Marian Mirilovic 2006-08-10 15:01:22 UTC 
I am startings performance tests on our Windows XP machine and it never finished.

I found out that the log file contains :
Connection refused: connect to 129.157.79.24 data class
org.ehucka.core.messages.ServerStateMessage

and if this message is printed tests never finished. The affeceted machine is 
"qa-perf-xp"

Eman, 
could you look at this please ? We haven't got results for Windows XP for few
days ...
Comment 2 ehucka 2006-08-16 11:32:53 UTC 
I do not know what could be wrong now. Public xp machine works without problems.
Could you provide threaddump of the machine when tests/test4u is blocked? Try to
get threaddump of xtest process too.
Comment 3 Marian Mirilovic 2006-08-22 16:15:42 UTC 
Now I found the problem, if the test run finished before any other test run,
it's fine , but if during test run, some task comes , the test run is still
running ...

How could I get thread-dump of the thread on Windows, if I don't have console ?

threaddump of netbeans
Comment 5 ehucka 2006-08-30 12:58:21 UTC 
I found out there were 4 running java processes - test4u, ant, xtest and
netbeans on a blocked machine. I cannot get ant's threaddump but test4u and
xtest were waiting for netbeans - only logging processes' output/error streams.
After I had killed the netbeans process, test4u continued.

Milo, could you look at the threaddump? Two threads are probably locked in
editor code. Thanks.
Comment 6 Marian Mirilovic 2006-08-30 14:28:13 UTC 
Mila confirmed that the problem is in the editor, so I am reassigning the issue
into the editor ...
