https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=248367 Bug ID: 248367 Summary: /sbin/ping fails when run many times simultaneously Product: Base System Version: 12.1-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: dseliv@gmail.com How to repeat # uname -a FreeBSD r 12.1-RELEASE-p5 FreeBSD 12.1-RELEASE-p5 GENERIC amd64 Run this line some times: # sh -c 'for i in $(seq 100); do ping -c1 127.0.0.1 >/dev/null & done; wait' It runs 100 ping processes in parallel. Sometimes some of them fail and produce such output: ping: unable to limit access to system.dns service: Socket is not connected That command is synthetic. In my real system I have this message even for 20 processes run to ping different hosts. The bug also presents in 11.4-RELEASE-p1. -- You are receiving this mail because: You are the assignee for the bug.help
