# NousResearch/hermes-agent · Dashboard PID probe fd leak fix via caching

## Open now

- Nothing open on GitHub.

A file descriptor leak was identified in the dashboard handler caused by repeated uncached PID status probe calls. The fix introduces caching for the gateway PID probe to prevent fd exhaustion in affected code paths.
