HS4 Pi suddenly stops executing events - like event engine is dead

[geeTee]

HS4 Pi w/o changes by me - suddenly stops executing events - like event engine is dead. has latest 4.27 sw. after several hours, Hs4 will no longer trigger time sensitive events (e.g. at 8pm do this....) nor when I press the Man icon to execute the event, either the event doesnt appear in the log w/o execution OR it doesnt even appear in the log again w/o execution.

rebooting the unit restores the functionality until the same issue several hours later.

Again I changed nothing for months!

What plugins are you running? Are you running any scripts with the RPi? Sounds like the little guy may be running out of memory. Disable the scripts if you have any and your plugins and test.

a memory check shows no loss of free memory. nothing changed. only concord and zwave plugin. lightly loaded unit. again it ran fine for 5 months since last change and now it is acting up.

You may want to backup your system and reimage the SD card as it could be having issues as a test.
