SGX memory leak during long-time usage

[OleksanderSalamatov]

Instances with our testnet SGX servers are working without reboot for almost three years now, and RAM and swap usage is high.
Seems like SGX have memory leaks during long-time usage without reboot.
SGX continue working when all RAM is used, but nodes experience high latency for SGX calls

SGX Version: sgxwallet_release:1.83.0-stable.1

Uptime:

Uptime: 987 days, 3 hours, 52 mins
Uptime: 1041 days, 6 hours, 2 mins

Memory usage:
For first server swap file was already existent


For the second server swap was activated for test of leakage

one of the problems is this

need to add corresponding changes to our code and re-check the memory growth
