Files getting stuck in the collector queue | CAVA

Dear All,

During last week, files which are getting scanned through CAVA are getting stuck in collector queue.

Users are facing File Hand Issue due to this.

To resolve the issue, everytime we are restarting CAVA Services.

What will be the root cause?

Thanks in Advance.
