sun.nio.fs.UnixException.translateToIOException

getting the following error in gatling:

**08:22:33** [client3] :gatling FAILED
**08:22:33** [client3] 	at sun.nio.fs.UnixException.translateToIOException(UnixException.java:91)
**08:22:33** [client3] 	at io.gatling.app.Gatling$.start(Gatling.scala:81)

Any idea why it came?

I ran gatling test on 5 nodes and it was an overnight test with 10K QPS in total.

Gatling version 3+
