3484321 - Work process crashes with "signal 7" while executing functions in the VMC

A work process crashes with "signal 7" while performing operations on a VMC (Virtual Machine).

At the same time, the "/dev/shm" is full or almost full. This can be checked with the operating system level command "df -h".

The C-Stack might end with the following functions:

J [date and time]
J  <VMC V3> <3> [7] Got Signal 7 at address 0x7f07f3c91000
M  <VMC V3> si_code = 2
