W3001 : Error while executing plugin

I am getting the following error during the output creation:

W3001 : Error while executing plugin: HTTP/1.1 500 Internal Server Error LoggedApplicationException: There was an error running the output creation process caused by ApplicationException: Communication error (OUT000019)
(SRV000042)

I know there are quite a few different error under the same code which isnt helpful, anyone have any ideas?

I have set the maximum memory to 2g via connect (the old .ini files seem to have dissappeared in the new 2018.1.1 version)

I note this issue here image display problems - General - Upland OL User community had a similar error and was related to an XML Data file issue. Some more information about the type of job you are trying to run, data format, etc would be helpful.

I have fixed the issue, it was due to the update to 2018.1.1 the engines defaulted to 640mb and 1 each, the .ini files no longer exist so I am assuming they found a different way to save the settings, I reset the values in the server config settings and believe this has fixed the issue, still having a problem running a job from the 11th as it hangs and launches 1 Weaver engine that just accumulates memory over over time and needs closing down through task manager.

They need a better way to manage these engines! I am spending more time fixing problems with PreS than running jobs!!!
