Package takes long hours to get from Queued to Running and then not canceling

Hi,
I have a package (165800) synchronizing Zoho tables into BigQuery.
This package is scheduled to run every hour.
This package has been running smoothly for years until recently.
In the last 2-3 weeks it is going into Queued state and stay there for very long time (sometime hours) before it starts executing. 
Based on your recommendation I changed the scheduling to run at hh:20 instead of hh:00. It seem to have solved the problem but on May 13 on run 324207216 it went in Queued state and stayed there until I tried to cancel it on the May 15th. From then on it is stuck on Cancelling state.

Please help me to reset the status of this run and also to fix the issue of entering into Queued stats for such a long time. I need a reliable synch mechanism
