groov EPIC processor may become unresponsive


Applies To:

Firmware for the following groov EPICs:

  • GRV-EPIC-PR1
  • GRV-EPIC-PR2
May also affect firmware for the following products:
  • GRV-R7-MM1001-10, GRV-R7-MM2001-10
  • GROOV-AR1, GROOV-AR1-BASE, GROOV-AR1-SNAP
  • GROOV-AT1, GROOV-AT1-SNAP

Versions Affected:

groov EPICs: All versions prior to 3.2.2
Other products: All versions

Resolved In Version:

groov EPICs: 3.2.2


Symptoms:

In rare instances, the groov EPIC processor may become unresponsive. You may see any of the following:

  • Module status LED on all modules turns red
  • Touch screen becomes unresponsive
  • No Ethernet communication
  • RAM usage steadily increases (indicating a memory leak)

Workaround:

Monitor RAM usage and restart the groov EPIC processor if available RAM falls below 64 MB. You can create a Node-RED flow to monitor RAM usage and restart the groov EPIC processor when it gets too high. To learn the basics of creating Node-RED flows, see "Developing and Deplying Node-RED Flows" in the groov EPIC User's Guide (form 2267).

Resolution:

Opto 22 has resolved this issue and will include the fix in an upcoming release.
