i'm using smokeping, after running for a while fping does not exit, it's taking full cpu resource (1 core) command line of fping is: /usr/sbin/fping -C 20 -q -B1 -r1 -i10 192.168.3.14 192.168.3.11 192.168.17.1 192.168.8.1 192.168.3.12 192.168.31.1 192.168.1.2 after some minutes digging i see weird thing: (gdb) p ev_first.ev_next $3 = (struct host_entry *) 0x7f1124aeed80 (gdb) p ev_first.ev_next.ev_next $4 = (struct host_entry *) 0x7f1124aeed80 (gdb) p ev_first.ev_next.ev_next.ev_next $5 = (struct host_entry *) 0x7f1124aeed80 (gdb) while $p.ev_prev p $p set $p = $p.ev_prev end $15 = (struct host_entry *) 0x7f1124af0080 $16 = (struct host_entry *) 0x7f1124aefd80 $17 = (struct host_entry *) 0x7f1124aefb80 $18 = (struct host_entry *) 0x7f1124aef980 $19 = (struct host_entry *) 0x7f1124aef880 $20 = (struct host_entry *) 0x7f1124aef780 $21 = (struct host_entry *) 0x7f1124aef680 $22 = (struct host_entry *) 0x7f1124aef280 $23 = (struct host_entry *) 0x7f1124aef080 $24 = (struct host_entry *) 0x7f1124aeef80 $25 = (struct host_entry *) 0x7f1124aeed80 $26 = (struct host_entry *) 0x7f1124aeed80 looks like 0x7f1124aeed80 is looping to itself according to bug report at https://github.com/schweikert/fping/issues/61 "fping 3.0 is old, and definitely looks like an old bug." please test and mark newer version of fping as stable i myself find =net-analyzer/fping-3.9 stable on amd64
