Try the latest version, there's a fix for armv7l crashes because of the native webp library. See #488

Please provide a complete log file.

[lordbeniel]

komga.log

please find attached, I've replaced the server name, file path and directory name with "<server_name>", "<path_to_comics>" & "<komga_dir>" respectively

[gotson]

komga.log

please find attached, I've replaced the server name, file path and directory name with "<server_name>", "<path_to_comics>" & "<komga_dir>" respectively

Those logs don't contain the error you reported before.

[lordbeniel]

this is the java error log it references
hs_err_pid18955.log

The komga server is currently being run from a screen session, the initial error report was copied from the screen session but screen does not show more historic logs.

what appears to happen is that the "scan library" task executes, this causes a java segmentation fault issue and the server then does not record more info to the ./.komga/komga.log file.

[gotson]

can you try to set KOMGA_NATIVE_WEBP=false ?

[lordbeniel]

same problem when

java -jar ./komga-0.91.0.jar --KOMGA_NATIVE_WEBP=false

is run

Segmentation fault

[gotson]

I am sorry, I thought you were on docker. For the jar please use --komga.native-webp=false instead.

[lordbeniel]

same error when running

java -jar ./komga-0.91.0.jar --komga.native-webp=false

Segmentation fault

it doesnt crash right away only sometimes when the scheduled library scan task is run. sometimes it can run through that and be fine

[gotson]

Can you get me the seg fault log /home/odroid/hs_err_pid1862.log?
