Memory leaks are tricky. It is important to make a distinction about what component is using a lot of memory:
1) the workers - analyzer issues and leaks in general would show up here.
2) the proxies - communication related
3) the manager - child - if the manager is overloaded the child will buffer log data
4) the manager - parent - if a logging destination is overloaded the parent will buffer log writes
If your manager processes are using a lot of ram, that doesn't have anything to do with the capture library in use.
