Error: F_JS0610 Timeout During Request

Issue

The following error appears in the HVR UI, causing the hub to become unresponsive and preventing web access while backend processes continue to run normally:

F_JS0610: Timeout during request

Environment

HVR 6

Resolution

To troubleshoot this issue, do the following:

1. Check the HVR_LOCATION_PROPERTY table in the HVR repository for excessive growth and a large number of entries.
2. Run the following command to remove stale deleted records, replacing <relevant-date> with the appropriate cutoff date:

   delete from hvr_location_property where delete_tstamp is not null and delete_tstamp < '<relevant-date>';
   

3. Confirm the UI loads normally after the cleanup.
4. Identify the process that is unexpectedly inserting property rows and address the root cause, or add monitoring and cleanup as a preventive measure.

Cause

This issue occurs when stale records accumulate in the HVR_LOCATION_PROPERTY table. A large number of old, deleted property entries can severely degrade hub UI performance and block access. This may happen when you configure a location to use load balancing across multiple agent machines with differences in OS platform, OS machine type, or OS kernel.
