QuickSearch runs out of memory and crashes the Editor when indexing thousands of assets

Unity: Editor Platform

Linux

Cannot Reproduce

6.0.X

2021.3.X

We are unable to reproduce this issue on the latest builds of Unity 2022.3 and Unity 6. We increased the number of objects by a factor of 10 just to make sure and were not able to observe the spikes in memory usage described on mac, Windows or Linux.

How to reproduce:
1. Open the user-attached project (U.AutoCopyFiles.zip)
2. Enable "Parallel Import" in: Project Settings > Editor > Asset Pipeline
3. Open the system's terminal in "[Project Path]/Assets/AutoCopyFiles"
4. Run: $python3 ./test.py
5. Return to the Editor
6. Press Ctrl+K to open the Quick Search window to start indexing the assets
7. Open the System Monitor and observe Unity's memory usage
Expected result: the Quick Search successfully indexes all the assets and doesn't run out of memory
Actual result: the Editor runs out of memory (the Editor may also crash)

Reproducible with: 2021.3.8f1

Reproducible on: Ubuntu 18.04, Ubuntu 20.04

Note: the issue is not reproducible 100% of the time and not on all Linux setups
