Hi,
It's a bit difficult to conclude what went wrong here. Socket is closed seems the backend server close the socket and therefore SPS tomcat server log report the issue.
Enable following logs will give us more hints on what happen
- httpclient log
- nohup.out
- web agent log
- web agent trace log
- mod_jk.log
- apache error log, apache access log
Thanks.
Regards,
