GC-100 Drops Communication

[davegravy]

My GC-100 spontaneously and sporadically drops communication. I don't know if this is a problem with my specific unit, GC-100s in general, or LinuxMCE. Sometimes the unit regains its connection and resumes normal operation on its own. Other times I need to reset the device (via webadmin, or reload router).

Here are some log samples from me switching a relay back and forth:

Note that linuxmce does not seem to retry its communications when no response is received, or to reset the device.

Has anyone experienced something similar?

Does anyone know (in the meantime until I can get this sorted out) how I can manually force reset the device from the command-line (without reloading router)?

I ran a test switching the relay once per second continuously from a bash script, and watching the link light on the GC-100 network card.

For the first 20 seconds it responds normally (1 flash per second). Then it gradually starts dropping requests until after a minute it is completely unresponsive.

Any ideas what might cause this?

Hi,
Did you see if the unit is also unresponsive with the GC utilities? See my (fairly) recent post, from Windows, Mac and possibly other OS'es you can directly communicatie with the GC100...
HTH,

I retried the test above using their itest.exe utility from windows, and did not have a single dropped request. Looks like it's LinuxMCE.
