What is this error??

[desgur]

Hello,

What kind of error is this? What can be the root cause?

After getting this error NX doesnt allow me to enter modelling/drafting or any applications or even to close NX. I have to terminate with task manager and start NX and then works fine.

Regards,

AK
NX 7.5.2.5

I guess without knowing that "PSMARK" says that Parasolid-something has crashed, and then probably the NX session is "halted".

Try Part cleanup on the part that you worked with. Save it and restart the session.
