memory leak in browser

after a update of the frontend from 2.0.2 or 2.0.3 (not sure anymore) tot 2.0.6.
i have 2 raspberry pi's with raspbian and chromium browser, they show 2 slide shows.
after some hours, chromium gives the message:
He's Dead, Jim!

Either Chrome ran out of memory or the process for the webpage was terminated for some other reason. To continue, reload or go to another page.

when i check the latest events of these 2 raspberry's it tells me they run out of memory and out of swap.

i have some more raspberry pi's with chromium to show other pages (non zabbix related), they dont run out of memory.
