Disable operation sprouting randomly after server restart

[ldlgds]

Hello,
A Zabbix monitor was down for some time due to insufficient disk space. We solved the problem, but now an operation I cannot locate into the interface or the DB is randomly triggered and its effect is to stop -without restarting- a worker on a monitored server.
How can I locate and disable this command?
Thank you in advance.

OK, the problem was elsewhere.
It was a task not linked to Zabbix.
