RAM leak to the MeshCentral server

[sheshko-as]

Describe the bug During operation, there is a sharp consumption of RAM until it runs out. I increased the amount of memory: it was 4 , then 8, now 16. Increasing the amount of memory does not help. I checked on a dedicated server: when the memory runs out, the service is running, but the memory is at the limit. I checked on the VPS server, the service restarts when memory runs out. The problem may occur once a day, perhaps once every three days, but no patterns have been found.
