pass3d-pool closing threads

[WlinkNET]

I got issue with stability of binary file when start I include 32 or 60threads my cpu support up to 80threads
after some time miner overload ./pass3d-pool and closing each thread. after they get lower to the 7-10 threads then we experience ram usage and swap usage until it crash totally if you leave it without supervision. you can check below picture for 9h of uptime server collapse totally

with this command started
./target/release/pass3d-pool --algo grid2d_v2 --pool-id d1DrnnYYFwynxpnZJork1TB8spm26AWaLPo7u9NukFQNSkoiK --url http://3dpool.cryptohood.org:9933/ --threads 32 --member-id YOUR_P3D_ADDRESS --key YOUR_SECRET_SEED(hex)
