Calculix has a memory allocation error

I used *restart several times in a program,read and run the calculix program several times, and finally got an ERROR: *ERROR in u_calloc: error allocating memory
variable=nodempc, file=ccx_2.21.c, line=279, num=-2142496261, size=4.

Does anyone know how to correct this mistake?

Closed because duplication with: Error running CalculiX
