Steps to reproduce:
Create simple perl script:
#!/usr/bin/perl -w use IPC::Run qw(run); run [ 'sleep', '5', ] or die 'Error from command';
You need perl and the IPC::Run perl module (in alpine it’s the perl and perl-ipc-run packages). Then you can set up an external check that runs that script and you only need to run the test on the item and it should crash the server.
It doesn’t happen when call perl’s sleep function, so that it’s happening because the script times out, while there’s still a forked process running.
Result:
zabbix-server | 1:20240613:111509.401 One child process died (PID:793,exitcode/signal:0). Exiting ... zabbix-server | 227:20240613:111509.401 HA manager has been paused zabbix-server | 591:20240613:111509.411 cannot write to IPC socket: Broken pipe zabbix-server | 591:20240613:111509.411 failed to request alert results zabbix-server | 227:20240613:111509.466 HA manager has been stopped zabbix-server | 1:20240613:111509.504 syncing trend data... zabbix-server | 1:20240613:111515.746 syncing trend data done zabbix-server | 1:20240613:111515.770 Zabbix Server stopped. Zabbix 7.0.0 (revision 49955f1).
Expected:
External scripts/Alert scripts should not cause server/proxy stop no matter the exit code or behaviour.
