Bug description

Visiting settings/admin/logging crashes Edge and Firefox.

You can scroll up and down a bit then CPU load increases dramatically. The size of the logfile is 26MB.

RAM usage increases by several GB in seconds

and then the browser tab crashes: "Out of Memory"

Firefox survives sometimes:

Lawkss commented 1 month ago

this is still happening in 29.0.3

just visiting logging page will immediately ramp up CPU fan and load.

LM-vb commented 2 weeks ago

The freezing/crashing does not happen to me any longer, since the update to 29.0.4. Can someone cross-check? The details of an entry not showing up, see #1275, however, still happens.

Ornanovitch commented 2 weeks ago

It is still happening with NC 29.0.4 on FF on my side...

LM-vb commented 1 week ago

No freezes on Chrome (127.0.6533.73), Firefox (128.0) or Safari on my side. That's weird.
