Package: iperf Version: 2.0.12+dfsg1-2 Severity: important Tags: upstream patch
When attempting an iperf run with 24 threads, I either hit a hang [*] or a bunch of "write failed: Connection reset by peer" errors [**]. These are both resolved by the following upstream commit: https://sourceforge.net/p/iperf2/code/ci/4565c2ce318318a8a1d4578bab78c0e03fb49437/ [*] $ iperf -c 192.168.86.2 -P 24 ^C^Cconnect failed:
