Hi,<br>
<br>
this problem should not occur in newer versions of midpoint (after
22.2. 2014 commit 9d85c21). This is caused by wicket-atmosphere
which was used as experimental module for ajax-push operations (task
notifications) but after commit on 22th February it was disabled for
now because other errors.<br>
<br>
So midpoint update should fix this issue, please do not forget to
run upgrade db script (2.2->2.3), there were some changes a
couple days ago.<br>
<br>
Best regards,<br>
<br>
<br>
Vilo<br>

I'm using Midpoint 2.3 development version from the 14th February
on Tomcat 6.0.36. Several times Tomcat has frozen up and according
to the jstack printout there is maxThreads=200 threads in the
parking state looking like the printout below. There is no big
traffic, it happend when I was testing the application alone. It
seems to me like some Midpoint bug.
