Hi Karl,
Thanks, Yeah I'll try to mock one up in C++ and see if i can reproduce it. (still working in java via javacpp so it can be tough to debug on my end). Will send you a C++ snippit soon.

You get a CL_OUT_OF_RESOURCES error if one of the previous kernels or data manipulations seg-faulted. Although unlikely, it may also be a problem with the matrix-vector product kernel. Is there any chance you can send a working code snippet to reproduce the problem?
