```auto
I had found that entries from one author present in previous libraries (Zotero and Mendeley) were not found when I searched in JabRef (“No entries present”). This seems to be an intermittent issue that occurs when I have hundreds of megabytes of swap memory under Ubuntu. I’ve also seen it under Windows.
My browser keeps chewing up more and more memory over time. If I don’t keep it open I don’t have this problem in JabRef
I have 8GB physical memory and a similar amount of swap under Ubuntu, so it isn’t a hardware issue"
```
This is a follow up issue, as multiple (likely) separate issues have been reported in the original thread. The original post is [here](https://discourse.jabref.org/t/best-way-to-merge-two-databases-with-large-overlaps/3267/9).

I wonder what browser you use that seems to have such a serious memory leak?
I did not know Windows also had a swap file. Good to know. I learned [something](https://recoverhdd.com/blog/swap-file-in-windows.html)

You might wanna check out [Vast Memory Consumption on Ubuntu 20.04 · Issue #8416 · JabRef/jabref · GitHub](https://github.com/JabRef/jabref/issues/8416) also, but i am not sure, if both of your problems are in fact related.

I’m using Firefox. Chrome is even worse.
Unfortunately I’m addicted to keeping more than ten tabs open at a time so that I can follow up an unfinished thought at a later stage 🙂
