Server not starting
My RapidMiner Server was working fine.I added python extension to my server.The server was not restarting due to memory issues on disk(as per logs as well).So I deleted some .mdmp files which were consuming a lot of space on that issue but after that when I am trying to start the server I am getting this error.

mmichel Employee, Member Posts: 129 RM EngineeringHi Niharika,
first you should verify that RapidMiner Server is not longer running (check for java processes).
Afterwards make sure that the '.r.lock' file within the $install-dir/bin directory is not existing (note the dot at the beginning of the name) - otherwise delete it.
If this does not solve the problem inspect the server logs and try to start server via standalone.bat and check if the error only occurs in case of a service start.
Hope this helps,
Marcel

mmichel Employee, Member Posts: 129 RM EngineeringHi Niharika,I tried terminating all Java process but it says no java.exe found.When I delete the .r.lock file it says can't be deleted as it is open in cmd.exe.
Then try to stop the cmd.exe which is attached the user SYSTEM. Otherwise you could also restart the OS to release the file lock.
"JBAS014803: Duplicate resource [(\"deployment\" => \"rapidminer-execution-0.6.3.war\")]"Please check the content of the standalone/deployments folder and make sure that only one version of the execution.war, broker.war and the server.ear is present. Also verify that the configuration/standalone.xml does NOT contain any deployments:
<deployments>...</deployments>
Cheers,

Be Safe. Follow precautions and Maintain Social Distancing
Thanks for the solution I was able to start the server.Can you please let me know the significance of '.r.lock' file?When the services get started '.r.lock' gets generated in same location.
I am again facing the same issue of my server not starting.I checked my task manager I dont see any java processes running but I am not able to delete the .r.lock file.
I checked the server logs possible error I found
Could not free resource of IObjectVersion ID-64717 from disk :java.nio.file.DirectoryNotEmptyException
Can you please help
if you are not able to delete the .r.lock file a process is still running and locking it. You can use for example taskkill to terminate all java applications which are running on the system:
Hope this helps,

I tried terminating all Java process but it says no java.exe found.When I delete the .r.lock file it says can't be deleted as it is open in cmd.exe.
I checked the latest logs the failures I detected :
I tried starting through standalone batch files but it starts and stops.
Also through process explorer I checked which process is running .r.lock file but it didn't show any file.
Screenshots of tasklist and error while deleting .r.lock file
Thanks for the help .I stopped the console window host from task manager and after that I was able to delete the .r.lock file and restart the server.
But still I am facing issue of my server stopping abruptly when I run a python code on server which is connecting to a elastic server and pulling data for further model building.
The process runs fine 2-3times but after that server stops abruptly.
I checked both the elsticsearch and jbossssvc.exe are crashing.So is the issue with my elastic server?
In the server file error is:
Could not free resource of IObjectVersion ID-64717 from disk :java.nio.file.DirectoryNotEmptyException
Caused by: org.postgresql.util.PSQLException: Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.
Further can we use same license key for more than one server?Would running both the servers at same time might cause any issue?
