Zeronet pages fails to load dynamic content (from DB) so i extracted ERROR lines from the debug.log and sorted removing duplicates, this is result:

Please do you see any helpful information that can fix something or what do you suggest to try?
Should i "just" quit ZN, delete content.db file and start it? Or something else i can try in order to prevent this issue in future?

The database corruption is in data/chart.db, so you need to delete that one.

The memory error is a harder problem, looks like it happens when the process has reached the memory limit from the OS.

Today i seen the memory error again on site when i was browsing it

Internal error: MemoryError():
UiWebsocket.py line 189 > MergerSite/MergerSitePlugin.py line 159 > 150 > Cors/CorsPlugin.py line 62 > 59 > UiWebsocket.py line 699 > base64.py line 58

currently the error reappear within like 1 seconds after i try to focus an image (bigfile) on Millchan site. Memory not appeared exhausted. After zeronet restart error does not appear. I guess it will take some time until start appearing again.
