When deploying to iProcess 11.1.0 with Business Studio 3.2.11 I had the following error message in an alert box:

Cannot connect to Staffware Dev.
Reason: Cannot obtain connection to server. I/O exception for
service:jmx:rmi///jndi/rmi://myserver.com:10025/server

In the log directory of the iProcess server I looked in the file swjmx_java.log and saw the following lines:

It turned out that one process did not properly terminate during a restart. After stopping the server and the ghost process SWRPCSVR the problem went away.
