Hi Mariangela,
Here is an update – seems this is a different issue as STRATOS-723.
After letting the system run for a few hours with the below mentioned commit
(8985d96eb811aa8e9ce2c114f1856b4c4e20517b) included.
I still see the same issue as you reported (with exception as below). The
stratos process is still running, no OOM yet but logging has stopped.
I think this is an issue which needs further investigation,
Regards
Martin

Hi Mariangela,
As an FYI, this was possibly caused by
https://issues.apache.org/jira/browse/STRATOS-723.
A fix was just checked in for this issue to 4.1.0, see commit
8985d96eb811aa8e9ce2c114f1856b4c4e20517b.

Thanks, Udara and Isuru for your quick response!
@Udara -
My file limit was 4000 and even after increasing it to 8000 I face the same
issue:
ulimit -Sn 8000

Hi Mari,
Good catch. Yes, the reconnection logic seems to be missing the connection
cleaning up part, in case an error occurs in connecting to the broker. Will
create a Jira to track this.

Hi Devs,
I got a message saying "could not connect to the message broker" even when the
message broker connection was already in place (started). There seems to be
some reconnection logic, which finally leads to a too many files opened error
(part of the log can be seen in [1]). When this happens the web browser on my
machine (Chrome) gets stuck and I have to restart Stratos to solve the issue.
Any idea how I can over come this issue? I have a feeling that this issue crops
up when Stratos has been started and left idle for a considerable duration
(i.e., 1 hr 30min).
