Hello, 
      I have a intermittent problem with a NI PXI-4461, I saw two cases: 
* First when I changed the PXI-controller in the chassis (I used to used two 8105 and 8106), the devices simply doesn't work. 
   - If I select the option Self-Test in MAX appears the next message. 
   (The device self test has failes. The error report from the device driver is as follows: Error -223022 occurred at Self Test) 
* Second If I let a long period of time (1 or 2 days) without use the device and I try to use it, again doesn't work and MAX report the same message. 
I need to reset the controller to can run the project that use the 4461. 
I only found this case but is not working...
