I also encounter the same problem. The jbpm.console.properties file is opened
several(hundred - in my case) times. I'm using the rest interface /new_instance for
creating processes.
Here is the output of lsof in linux on my test machine:

Yes that a known issue with Mina and Linux.
You should increate the number of files that can be opened in your OS.

I set echo 30 > /proc/sys/net/ipv4/tcp_fin_timeout and restart networking service and
then increase *Increase The Maximum Number Of Open Files / File Descriptors (FD) to
1000000 but the problem is not resolved.*
If I decrease tcp_fin_timeout to 10 secondes *Too many open files* happens more than the
time tcp_fin_timeout is equal to 30 or 60 seconds .
any help appreciated.

Yes it should be fixed in 5.3, if you still have troubles please create a jira issue for
5.3

Hi Mauricio, what was the actual fix that was done to the codebase (class/method) to
resolve this issue. We are uisng JBPM 5.2 and at present moment have no capacity to
upgrade to 5.3, so would like to see if we can patch our 5.2 release with this fix.
Thanks, Ash.

Jonathan, this would just delay the issue. As over time I can see these handles increasing
until our application is restarted.
Mauricio, what was the actual fix that was done to the codebase?
