SOLVED: Browser freeze/crash on certain pages
« on: April 23, 2019, 20:42:44 pm »
Hello,

We are facing a really weird problem the past few days (or at least we noticed in this timeframe).

Certain VM pages lock-up the browser tab, making any page interaction un-responsive. The issue happens with Chrome mostly, but also has been observed on Firefox (3 different PCs so far).

The browser freezes, requiring a force-close of the tab (which takes a few seconds to occur). CPU usage for the browser also goes way high.

Two sample pages where the problem occurs:
*** removed ***

Sometimes the problem occurs instantaneously, other times, it takes some time to occur.

Online website malware scanners show no problems so far.

And we cannot troubleshoot with browser developer tools, because they freeze as well and are not usable.

Any help appreciated... thanks!

The problem seems to be on the client side (browser). The browser tab freezes causing high CPU on the user's PC. Doesn't seem related to the server.

I updated some scripts in the template files.

3rd party template was using an old jquery 1.11.1 version. I replaced it with 1.12.4.
Problem seems to be solved, I cannot reproduce anymore.

Thanks everyone
