I tried reproducing it on few different machines, but I am not able to see it. It would be great if you can help me a bit more, so that I can figure out what went wrong in your case. It seems that the recording itself was successful, but later KernelShark fails to open the recorded file. Note that the file (trace.dat) must remain in the directory where you started KernelShark even after the abortion. Please try to open again this file in KS and check if this gives you the same error. If this is the case, send me the trace.dat file, so that I can investigate further. Thanks!
