I'll try running some tests also on other architectures, including arm64 and s390x (to catch potential endinanity issues).
I tried debugging nperf in arm64, with the below patch: diff --git a/client/main.c b/client/main.c index 429634d..de1a3ef 100644 --- a/client/main.c +++ b/client/main.c @@ -63,7 +63,10 @@ static int client_init(void) ret = client_set_usr1_handler(); if (ret < 0) return ret; - return ignore_signal(SIGPIPE); + //return ignore_signal(SIGPIPE); + signal(SIGPIPE, SIG_IGN); + + return 0; }

Any idea what went wrong here?
Also, Would you mind running netperf to see if there is similar issue in your system?
