:

Caused by: java.io.IOException: Too many open files
	at sun.nio.ch.IOUtil.initPipe(Native Method)
	at sun.nio.ch.EPollSelectorImpl.<init>(EPollSelectorImpl.java:49)
	at sun.nio.ch.EPollSelectorProvider.openSelector(EPollSelectorProvider.java:18)

This should be the cause - please increase open file count limit:
