I got my first 2.3.6 graph stop crash last night, and it still took out NRecord. The difference now is that all of NRecord hung; before 2.3.6 some of it would still survive, like the EPG update routine. You can see from last night's log that it just stopped doing anything at 2am.
I do have the patch you posted to get rid of the crash.mdmp pop-up, so I got a crash.mdmp but no interactive services pop-up.
When I looked at the task manager after the crash, neither NRecord nor NDigitalHost were running.
