2.12.1.1. Concurrent script execution blocked

Errors "Concurrent script execution blocked" in the cron log mean that the task launch frequency is less than its execution time. As a result, an attempt to launch a new instance of the task is blocked because the previous instance of the same task has not completed its work.

Possible solutions to the problem:

• Increase the interval between task launches.
• Reduce the task execution time (optimize the command or script being launched).
• In the cron task settings, select "When starting a new process, stop the previous one" for the "Simultaneous launch" option. ⚠️ Use this if forced termination of the launched command or script is not critical and does not entail any consequences (data loss, etc.).
