One page of HubSpot open using 7GB of memory

jh99 — Sat, 08 Nov 2025 23:33:37 GMT

Is there a memory leak currently with the hubspot CRM? I only have one page of hubspot open and it's taking 7GB of memory... That's insane. Please support.

This issue occurs even after clearing cache by the way.

That's a lot of memory try clearing the cache of your browser or disabling any extension that feel problematic and also test in in incognito window to see if it still spikes.

Same here - this time on Mac - clearly a memory leak.

All standard troubleshooting methods do not help. Individual tabs start using up all available memory. After a few minutes, the browser becomes unresponsive.

I have to close all tabs every few minutes - It will work but minutes later same problem. I had this going on for months.

Using Safari Mac with M2 and newest OS

This is a critical error for me that makes working with HubSpot a drag - please help.
