[CRIU] Need help with Analysis (some Kernel Features are Missing

[LUBEPlays]

Hello,

I am here writing to you because in your WIKI (criu.org) you recommend 
users to write you an E-Mail like this one to get help. I am trying to 
get the --extra features to work, because I want to able to save and 
load the state of Carla (JACK Plugin Host) and QLC+ (DMX Host). I am 
currently getting the error "Looks good but some kernel features are 
missing which, depending on your process tree, may cause dump or restore 
failure.". I Can't dump Carla or QLC+ at the moment. With Carla I get 
the error "Error (criu/sk-unix.c:871): unix: Can't dump half of stream 
unix connection." with the use of --ext-unix-sk and --shell-job. With 
QLC+ i just straight up get the error "Error (criu/files-ext.c:94): 
Can't dump file 15 of that type [20660] (chr 116:1)" and "Error 
(criu/cr-dump.c:1635): Dump files (pid: 1588) failed with -1". I hope I 
can get help here, because it's so annoying to constantly restart carla 
after a crash...
