Some times starting MWA services you may get following error:
[user@node] $ sh mwactl.sh start 10208
MWA Telnet Server Release: 18.104.22.168 [December 12th 2002]
[user@node] $ Couldn't create server socket : Address already in use
When we checked port 10208 at OS level it is occupied by concurrent manager process.
[user@node] $ netstat -nape |grep 10208
tcp 0 0 ::ffff:10.131.64.10:10208 ::ffff:10.131.64.10:31288 ESTABLISHED 502 64085 19765/java
[user@node] $ ps -ef | grep 19765

Also sometimes while staring the services, one will get following error in error_log:
[Tue Oct 7 00:10:33 2014] [crit] (98)Address already in use: make_sock: could not bind to port 4473
user@node:/u01/oracle/SID/inst/apps/SID_host/logs/ora/10.1.3/Apache #sudo netstat -patun | grep 4473
tcp 0 0 10.129.11.77:4473 10.129.11.75:1561 ESTABLISHED 31618/FNDLIBR
Also if customer has multiple EBS installation on the same box, it is likely that one of the random port used by OS may clash with a port used by EBS.
This leads to fs_clone and similar utilities to fail.
Some times you may also get following error while starting JOC in javacache.log-
Cache not initialized
The port 12345 should be free on each host running the JVMs
If you check port 12345 at OS level it may be occupied by OPP/Workflow processes. You can check that with netstat command as shown in Scenario 1.
