I set up a task in Lucee Web Admin to run every 10 seconds (also tried 20 seconds). It runs fine for a while but then after 10-20 minutes, it quits running (all other scheduled tasks also stop running). I cannot manually “execute” any tasks listed in Scheduled Tasks via Admin, and only a restart of Lucee solves the problem (of course, the issue re-occurs after 10-20 minutes!). See error information below.
The task takes <2 seconds to complete, and just in case there was an issue of task taking longer than frequency interval, I set the request timeout for the task to less than 10 seconds. Unfortunately, that doesn’t help.
Any thoughts on what could be happening? Is running tasks with frequency of less than 30 seconds an issue with Lucee?
Thanks,
Cage
