The problem seems to be on the server where 'application2' is running.
The best cause I can figure is that Firewall / Antivirus software (temporarily disable to test) is interfering.
Some searches seem to suggest more than one application binding to the port (two IDE's in particular), check your processes and/or restart the server (webserver or host). However I am not sure how that is possible unless they are using UDP instead of TCP.
Commenting:
Since "frequently", i assume "not constantly", so "sometimes works".
Answer:
Your problem can be localized "around":
com.me.opmanager.extranet.remote.communication.fw.fe.RegionalListener
.doPost(RegionalListener.java:87)
..and it is definitely IO related! I fear it is not a big help after 3.5 years
It seems this class belongs to OP manager.
