[SOLVED] System slows down, Unknown Error messages

@helmar74

Where did you saw this?

addons.config

@helmar74

binding=“avmfritz,exec,tinkerforge1,wol1,fritzbox1,fritzboxtr0641,network,kodi,astro,amazonechocontrol,gpstracker,panasonictv1,mqtt,openweathermap,zwave,dwdunwetter,http1”

@helmar74

transformation=“map,regex,xslt,exec,javascript,scale,xpath,jsonpath”

@helmar74

I just noticed you have exec as a transformation and a binding. I do not know if that is correct.

I have both install on my system without issue.

[helmar74 (Helmar)]

Maybe I’m not guessing it right…
But how do I “correctly” clear the cache and delete tmp folders?

clearing the cache & tmp folders

I always have done it that way:

1. stopped openhab
2. sudo openhab-cli clean-cache
3. rebooted system (twice or three times)

How do I delete tmp folders?

Thanks a lot

[Bruce_Osborne]

I go old-school.
Shut down openHAB
Assuming userdata is /var/lib/openhab2

sudo rm -rf /var/lib/openhab2/cache/*
sudo rm -rf /var/lib/openhab2/tmp/*

Restart openHAB

That deletes the contents but leaves the directories.

After sudo openhab-cli clean-cache
both directory were deleted …

both directories were created after first reboot again

@helmar74

After sudo openhab-cli clean-cache
both directory were deleted

That is what openhab-cli does but when troubleshooting its worth trying both ways just to make sure.

[helmar74 (Helmar)]

OK, thanks.
I rebooted after clean-chache and now have to wait until system is up again… will take a while

[Bruce_Osborne]

@helmar74

both directory were deleted

Are you sure you put the / between the directory name and * ? Leaving it out would delete the directory too.

[helmar74 (Helmar)]

I didn’t deleted manually I only used sudo openhab-cli clean-cache

[helmar74 (Helmar)]

After first reboot I got a lot of error messages, that items are missing
rebooting second time

[Bruce_Osborne]

After I first upgraded to 2.5 my text files were not read until a restart. Likely a bug in OH Core that will not be fixed.

[helmar74 (Helmar)]

second restart is in progress. All items are there now… waiting until restart is complete (currently loadubg rules)

[helmar74 (Helmar)]

Second Restart finished.
Current situation:

and no errors or warnings in openhab.log
Normally after a 30-60 minutes the load raises up… will check

[helmar74 (Helmar)]

Now the errors and the load is here again:

[Bruce_Osborne]

I see Tasmota mentioned. Would it make sense ti uninstall that binding temporarily as a test or would that be too disruptive?

If Google Translate is correct, the error occurs about 6 seconds after an Item change. Item ACEF7C could also be the issue.

[helmar74 (Helmar)]

@Bruce_Osborne

ACEF7C

@Bruce_Osborne

ACEF7C

ITEM ACEF7C is a 433MHZ Code… send via Tasmota RF Bridge
