Description Yan Pas 2015-08-24 09:32:11 UTC 
User-Agent:       Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.155 Safari/537.36
Build Identifier: LibreOffice 4.4.5.2

Libreoffice automatic spell-checking (underlines unknown words with red line) eats too much RAM. For example for 60k symbols odt document - 40MB of RAM. Moreover when the document is closed - this RAM isn't loaded out (mem leak) see also #92482

Reproducible: Always

Steps to Reproduce:
1. Open attached doc with disabled automatic spellcheck, measure ram
2. enable auto spell-checking, measure ram
Number of unknown words does not correlate with amount of ram been eaten

My RAM usage for soffice.bin increased 4 MB.

What is your result with 5.0.1?

Linux 3.16, all extensions off, version 5.0.1 - plus 20MB of RAM. With one extension enbled +30 MB of RAM. Also closing this document or disabling grammar checking doesn't reduce mem usage - memleak. See also #92482
