Memory leakage in Zotero 7 on Apple silicon ?

kevin-yuan · April 17, 2024

As suggested, the post was moved from : https://github.com/zotero/zotero/issues/3976.

Memory goes high to 6+ G with just one single small (3 pages) pdf file open.

- Reference

Actions taken:

I tried to disable plugins and restart the app, the issue alleviated but the memory usages is still often 3+ G.

So then it sounds like this was caused by one of your plugins.

You could see 3 GB usage if you have multiple large PDFs open. It's only a memory leak if it doesn't go away when you close the PDFs, or if you see figures that high with only a single small PDF open.

My Zotero consume 6GB of memory (without closing for a few days), so I started to dive in this issue and made some tests.
Plugins installed:
- Better Notes for Zotero
- Ethereal Style
- Translate for Zotero

open 3 pdf files (disable plugings)

After closing pdf files (disable plugings)

open 3 pdf files (enable plugings) is basic the same memory usage as (disable plugings). But closing pdfs did not release memory.

then, I reopen these 3 PDFs, memory consumption achieve about 6GB

repeat these process, memory consumption achieve 8GB

I made some test on these plugings. It's obviously that Style leaks the memory.
I have reported this to Style developer. It seems that Style stop some garbage collection of Firefox(Zotero)
