Repeated errors if >1 matlab open using project

[narcolepsy]

I get the following error which I am trying to narrow down to either

• autocleanup of /tmp
• multiple instances of MATLAB + project both trying to write to same log file

Caused by: java.io.IOException: Stale file handle
	at java.io.FileOutputStream.writeBytes(Native Method)
	at java.io.FileOutputStream.write(FileOutputStream.java:326)
	at org.apache.logging.log4j.core.appender.OutputStreamManager.writeToDestination(OutputStreamManager.java:250)
	... 51 more

I have checked out the code but can't get ./gradlew clean test to run correctly:
