Hei
I recently updated a working system to LV2013 from LV2012 happy for fix of a bug on the time (X) scale of charts not displaying correctly.
The system is running on a cRIO-9074 and remote front panel is utilized for monitoring.
Some home-built code for controlling the number of connected WEB-clients is constructed and has been performing well with the LV2012 software set (LV, LV-RT, cRIO software).
Upgrading to LV2013 (Complete upgrade of development PC & cRIO to 2013) I am experiencing problems when trying to disconnect a client with the "RP.Close Connection To Client" node. It is doing its job, throwing out clients as wanted but the CPU of the cRIO stalls to 100% immediately after disconnect.
Using the NI Distributed System Manager the system is normally running at a load of 20% (Normal Priority)
After disconnection, the CPU loads goes 100% with 40% Normal and 60% High priority.
It seems like some system object is going into tight loop!
After the CPU goes 100% the system response is gone, a reboot is needed.
Any help is appreciated, a simplified VI that shows the problem is attached.
