hi, I am trying to get elasticsearch to work in an embedded mode inside a websphere application server (V8.5.0.1) on Z/OS. After startup, it keeps logging the below error trace and the CPU spikes to 100%. - [ZOSB] version[1.0.0], pid[50397324], build[a46900e/2014-02-12T16:18:34Z] - [ZOSB] initializing ... - [ZOSB] loaded [], sites [] - [ZOSB] initialized - [ZOSB] starting ... - [ZOSB] bound\_address {inet[/0.0.0.0:9300]}, publish\_address {inet[/10.1.99.130:9300]} - [ZOSB] exception caught on transport layer [[id: 0x504824fd, /10.1.99.130:25601 =\> /10.1.99.130:9300]], closing connection java.io.IOException: EDC5112I Resource temporarily unavailable.

There is a defect with a similar stack trace listed on IBM - [http://www-01.ibm.com/support/docview.wss?uid=swg1IV50158](http://www-01.ibm.com/support/docview.wss?uid=swg1IV50158). It is fixed in versions 6.0.15.1, 6.1.7.1 and 7.0.6.1. However, these versions are not available for Websphere on Z/OS currently. I tried the same version of the SDK on Windows 64-bit and it started up fine. Do you have any pointers on what might be causing this issue? Thanks, Binoy ---
