OpenCL SDK can't find valid license file

Thank you, I saw the Nallatech debugging thread.

The license settings are actually shared between all of the servers, both functioning and nonfunctioning - a common configuration file is used to set the environmental variables. Just to double check though;) I've used

 printenv | grep LM_LICENSE_FILE 

which returns the settings on the server concerned. I've also tried removing the settings in the Quartus II GUI to no avail.

My suspicion is that there is something strange going on with a library that flexlm is using and so the OpenCL SDK license lookup is failing. I've tried

ldd $(which aoc)

, but everything seems in order.
