Error executing uvccapture command. returned: 9 [Solved]

[jluc2808]

hello,
since a few days, i have an error in domoticz logs : Error executing uvccapture command. returned: 9 which is new and append without any modification on my dzvents scripts (for a long time).

whhen this error appends, all my dzvents script seems stopped (no more update on any devices which used dzvents script) and when i look at parameters/others/dzvents the swith for dzvents is OFF (i never touch this switch)

as i don't find what is the error code : 9 and i don't make any update to domoticz / synology / dzvents
could somebody give me a way to search ?

thanks
jluc

Please share the relevant loglines also a few line before and after the error please. The string "uvccapture" is related to a camera snapshot but I don't see a direct link with dzVents code .

Sorry but I don't see any reference to dzVents here. Need to have more detailed logging before anything can be said about what's causing this. Can you enable debug logging for domoticz / dzVents ?

Of course, when this problem/error append all the dzvents script are frozen and stop running, so even if I set the debug mode you will never have dzvents logging.
Read carefully my 1rst post, I have discribe the effect, param/other/dzvents is disable and no more dzvents script running.

I red and understood your first post. Debugging is available at various levels; that is why I asked to turn on debugging for both domoticz and dzVents.
When dzVents stopped it will no longer produce any debug info but until then it might reveal something that is happening on your system.

OK I understand, I will set to debug

some news ,

after a long search i tried to connect to my NAS with SSH session and get a strange warning : ERROR: ld.so: object '/usr/local/lib/libkk.so' from /etc/ld.so.preload cannot be preloaded (cannot open shared object file): ignored.
so i search that problem and find that there is virus / worm https://www.domoticz.com/forum/viewtopi ... =6&t=28329 which is involved in the problem, so i think that all my problems could be the result of that worm.
i will stop this thread and go back to the worm one.

thanks a lot
