Thanks. Can you remember what you were doing at the time? Had you edited and closed tracks or mosaics before trying to add this one? A sequence of events might help us try to reproduce this problem.

Viewing number of logs to select proper segments, 5 or 6 tabs with logs were opened at the time of crash. Task manager showed that RM takes near 12 gb of memory (from 16 in computer).
And I've found that this segment was added to mosaic, i.e. RM crashed after successful segment insertion.
This crash reoccurs from time to time.
