Memory leak in plugin? #51

Closed guitardoc closed 10 months ago

guitardoc commented 10 months ago

I use the plugin for quite some time. It seems to open up numerous instances of chromium after a while: This is a memory snapshot from 10 minutes after booting the Raspberry Pi:

Already 13 instances of /usr/lib/chromium/chromium are open now and they use more memory than before.

The Website to Camera plugin is the only application that uses chromium on my Raspberry Pi, so I think there may be some memory leak in it or in Chromium itself. Could you please have a look at it?

Thank you very much.

On second thought this is probably the normal behaviour of Linux memory management. It can be closed I think.
