    We are connecting in floating window mode to an NX server (CentOS) to run Cadence applications. When displaying simulation waveform data, the client will randomly close with the error log

    Module: C:\Program Files (x86)\NoMachine Enterprise Client\bin\nxclient.bin pid 77220

    Thread: 44768 exception 0xc0000005, ‘Access violation’

    The session on the server side is not affected — simply re-opening the session brings back all windows (albeit pixelated until they are redrawn).


    We have a fix for a similar problem included in the next maintenance release which has been scheduled for next week. Looking at the errors you pasted, it is possible that this could solve your problem with Cadence. I would wait to try that first.


    This was fixed in the 7.9.2 update
