Hi again ;) Umonitor suddenly stopped working from one day to another ?

Hello :) Could you give me the output of

umonitor -l portable --verbose?

Thanks!

Notaduck commented 6 years ago

Yes of course 

umonitor -l portable --verbose

Hmmm I need more information about the segmentation fault. Could you use valgrind and run the following?

valgrind --leak-check=yes umonitor -l portable --verbose

I'm first home again tomorrow, but I Will do IT as soon as I get home

Is that the complete output of valgrind? Where's the segfault?

Thanks! Could you post your configuration file? I suspect the problem might be there.

this issue sounds similar to mine ;)

rliou92 commented 6 years ago

I identified the commit that introduces the segfault, so I reverted it. Try it now!

Notaduck commented 6 years ago

@rliou92 I can confirm that everything is working now, However it is on a new install I tried it
