|Title||tcp_conn_stat: resolve latency problems introduced by ss|
|Checkmk Edition||Checkmk Raw Edition (CRE)|
|Compatibility||Incompatible - Manual interaction might be required|
On some systems the ss command used for the tcp_conn_stat check introduced latency problems. To resolve this issue by default now "cat /proc/net/tcp /proc/net/tcp6" is used again. ss is only used as a fallback if cat runs into a timeout.
Additionally, the maximum waiting time for cat is reduced from 10s to 5s and SIGTERM is sent by waitmax instead of SIGHUP.
