Hi, Yesterday, I upgraded our xymon monitoring servers to 4.3.30. We have approximately 70 instances running and on 4 of them, the xymond_rrd that's monitoring the status channel module crashes. When running in debug mode, I noticed that it crashes on messages with garbled NCV messages. This includes devmon messages, but also the Synology client message. Example of a bad devmon message that crashes xymon_rrd: Free memory= bytes (Regex mismatch%) xymon_rrd debug output: 18326 2020-11-02 23:06:33.529013 xymond_rrd: Got message 156827 @@status#156827/axidrnsw5|1604354793.510204|127.0.0.1||axidrnsw5|memory|1604356593|green||green|1600168997|0||0||1600078261||Network-LAN|0| 18326 2020-11-02 23:06:33.529018 startpos 41059, fillpos 54529, endpos 41610 2020-11-02 23:06:33.936070 Peer at 0.0.0.0:0 failed: Broken pipe 2020-11-02 23:06:33.936133 Child process 18326 died: Signal 6 We didn't experienced it on previous versions.
