https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D281560 --- Comment #21 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to shailend from comment #20) Then, this is especially looks like a live-lock. User thread should not have the priority 4, it is in the range of prioritie= s of the interrupt threads. Since the iperf thread owns the lock, and driver th= read contends for the lock, most likely it is the result of priority propagation. In other words, iperf thread must drop the lock to allow the system to make a progress. Perhaps it should do so after processing some fixed amount of work. --=20 You are receiving this mail because: You are the assignee for the bug.=
