SMBJ PacketReader thread leak in DirectTcpTransport #1992
Description
The plugin leaks SMBJ PacketReader threads when Windows agent connections close unexpectedly (EC2 termination, network failures, timeouts).
The root cause looks like a bug in SMBJ library, just reported at hierynomus/smbj#882 but there are concerns about the project's maintenance:
- Last release: v0.14.0 (2024-12-09)
- Some PRs merged in early 2025 but not released
- Multiple 2025 issues without response (some question project is still alive)
We could consider pushing/contributing for a new release that includes a fix, or, if no other options, explore an ugly reflection-based workaround to access the thread and call stop, though this approach is admittedly a workaround.
If anyone has more experience with this SMB lib, your advice or input would be much appreciated before I continue.
