Possible memory leak #195

Closed ArjenR closed 4 years ago

ArjenR commented 4 years ago

Hi,

I think there might be a memory leak. When I run the script from the console (within a docker container) I see my availalble memory run down quite quickly until the script gets killed by oomkiller.

This is might be when the previews are generated for text files.

Same problem here, but not text files, only pictures:

sudo -u apache php /usr/share/nextcloud/occ preview:pre-generate -vvv

duplicate to https://github.com/rullzer/previewgenerator/issues/194

problem still existing. as commented in #194 it seems not to be related to this app. is there any ticket for nextcloud itself, for fixing that bad behaviour?

This is most likely an issue in the Nextcloud server. Nothing this app can fix.
