pna-x Cal All number of channels limitation?

Hello,

I'm running the N5244A PNA-X with firmware A.09.90.01. I tried running the 'Cal All' using the following types of channels:

-5 narrowband SMC channels
-5 wideband SMC channels
-5 noise figure for converter channels
So a total of 15 channels in all.

I am using 2 ecals: A 2.4mm and a 2.9mm E cal kit.

It took nearly 5 hours to nearly finish the calibration. However, when it got to the last step  (after the thru adapter characterization step) to save the calibration, the application crashed! (please see attached png). I've attached the crash log in a zip file. 

When I restarted the application and went to the cal set manager, there was nothing I could salvage, since no cal set registers was saved at all,. 

My question is whether there is a limit on the number/type of channels I can 'Cal All' at any one time, so I can avoid this unpleasant situation. 

Also, as a UI feature enhancement, is there a way to put an audible alert during the 'Cal All' process when the next step is ready to go? Between power cal and the next step was about 3.5 hours, and I don't want to be polling the station all the time.
