[Bug][Question] Covenant Team Server Memory Consumption

When using Covenant normally on a Ubuntu Server, after some time of use memory use spikes gradually until the oom_killer kills the Covenant process. I tried resizing the vm several times, from 4GB up to 16GB, but the problem persists and eventually covenant server crashes. I don't know if the HW requirements are not meeted in my scenario or there is a bug.

dmesg [2385505.072155] oom-kill:constraint=CONSTRAINT_NONE,nodemask=(null),cpuset=/,mems_allowed=0,global_oom,task_memcg=/user.slice/user-0.slice/session-759.scope,task=Covenant,pid=210546,uid=0 [2385505.072259] Out of memory: Killed process 210546 (Covenant) total-vm:40059000kB, anon-rss:15893864kB, file-rss:0kB, shmem-rss:8kB, UID:0 pgtables:33284kB oom_score_adj:0 [2385505.384048] oom_reaper: reaped process 210546 (Covenant), now anon-rss:0kB, file-rss:0kB, shmem-rss:8kB

Describe the feature request or bug When using Covenant normally on a Ubuntu Server, after some time of use memory use spikes gradually until the oom_killer kills the Covenant process.

To Reproduce Steps to reproduce the behavior:

1. Start covenant via detached screen screen -dmSL covenant sudo dotnet run -p /opt/Covenant/Covenant/Covenant.csproj
2. Connect grunts to covenant In this case whe tested msbuild launcher
3. Execute normal commands in the grunts
4. Import powershell modules (like invoke-mimikatz.ps1, powerview.ps1, etc.)
5. Execute modules locally or via remoting in other hosts 5'. Or Execute commands in a grunt
6. The memory use spikes and Covenant proccess dies

Expected behavior Covenant server should not crash

Target Information (System that implant is running on):

• OS: Windows 10
• Version Windows NT 10.0.19042.0

Additional context Looks like the problem gets worse when importing more than one powershell module. Y some cases after a few days of operation suddenly the memory comsumption spikes at every command executed in any grunt.
