I can stably observe that when using Trojan as the server, there will be memory leak issues.
When I investigate the problem, I found it related to the fallback. I mean that the problem is particularly obvious when fallback address is not set.
After code auditing, I fixed a possible leak, but I can't guarantee that the problem was completely repaired, because I have not conducted further testing.
