MID Server service on Linux won't start with error in wrapper log stating the mid.pid file already exists
MID Server won't start with the following error in the wrapper.log file:
A situation could occur where a process with the pid exists but it is not the correct process. Although this can happen in a number of cases, the most common is during system startup after an unclean shutdown. Usually the mid.sh script will handle these situations. However, if the pid file is still stale, rename the mid.pid file in the /agent/work directory and try to start the MID Server service again to bring the MID Server up.
