groov View hangs due to lag in computed tags


Applies To:

groov View running on the following:

  • GRV-EPIC-PR1, GRV-EPIC-PR2
  • GROOV-AR1, GROOV-AR1-BASE, GROOV-AR1-SNAP
  • GROOV-AT1, GROOV-AT1-SNAP
  • GROOV-SVR-WIN, GROOV-SVR-WIN-BASE, GROOV-SVR-WIN-SNAP

Versions Affected:

GRV-EPIC-PR1, GRV-EPIC-PR2: 3.0.0 to 3.2.1
All other products: groov View 4.3a to 4.3c

Resolved In Version:

GRV-EPIC-PR1, GRV-EPIC-PR2: 3.2.2
All other products: groov View 4.3d


Symptoms:

You may see the values of computed tags lag significantly behind real-time; for example, the computed value reflects input received minutes to hours earlier. Sustained high CPU usage by another process on the groov device (for example, Ignition Edge on a GRV-EPIC-PR1) will likely cause this issue. Eventually, groov View may stop responding.

Workaround:

Try the following options:

  • Use fewer computed tags.
  • Move processes with high CPU usage to another groov device or system.
  • Look at ways to reduce CPU usage.

Resolution:

Opto 22 has resolved this issue.
