What causes this?

I have noticed several of these in my Activity log, does anyone know what the cause is please.
[system] reset expired queue_id 99286 in jrCore/minute_maintenance queue - worker id 2524150 - exceeded queue work time
updated by @ukdenny: 12/29/19 09:27:51AM

It means that a task that has been queued to run has failed to complete in the maximum allocated time for it.
If you click on the '?' to the right of the row there might be more info on what the task was.

Hello Paul,
Is there anything I can do ? Does it need fixing? Here are the details from the ?
Array
(
[info] => Array
(
[queue_id] => 105801
[queue_name] => minute_maintenance
[queue_system_id] =>
[queue_created] => 1569835382
[queue_module] => jrCore
[queue_worker] => 1062124
[queue_started] => 1569835382
[queue_expires] => 1569835437
[queue_sleep] => 1569835382
[queue_count] => 0
[qtime] => 1569837103
)

[data] => Array
(
[minute] => 1909300923
[_post] => Array
(
[_uri] => /sumoruggedtablet
[module_url] => sumoruggedtablet
[module] =>
)

[__queue_worker_timeout] => 55
)

This is the 'minute_maintenance' event that is queued every minute and times out at 55 seconds. If there was a serious issue your activity log would be full of these messages (one a minute). You say that you only have a few reports of this so I'm guessing that it only happens when your server is busy with other stuff and doesn't get around to this task in time.
The only module that you're likely to have installed that uses this event is the Mailer module and that is just collecting stats with it, so likely not critical to anything else, so I'd be tempted to let it go, but maybe keep an eye on it to make sure it doesn't get any worse.
