Hello, I get close more than 900mbps today with recv_buf=4194304, send_buf=4194304 and max_buf=8388608

I have a .net process running in an LX zone that sometimes "gets stuck". However, if I run /native/usr/bin/pstack on the process it immediately works again. Anyone seen something like this before? (Still running on joyent_20250306T000316Z which is a bit older)

presumably something is causing the .net process to SIGSTOP, and the side-effect of running pstack on it is that it gets a SIGCONT afterwards?

what does pflags tell about the state?
