149607 - Mozilla does not free memory

Status: VERIFIED DUPLICATE of bug 131456

(SeaMonkey :: Tabbed Browser, defect)

Description

[Raul Dias]

This might or might not be related to TAB-Browsing.

When opening several pages with tab browsing, the memory usage increases with the
number of pages and its memory load (as expected0).

However, closing the tabs does not frees used memory.
Worse, the memory load from about 20 tabs to 1 tab increased from 49MB to 58MB
of RSS.

At first I thought that mozilla acted as perl that does not frees memory to 
be able to quickly reuse it.

However, opening new pages increased the memory usage, which means that 
the memory is not being reused.

This might even be a slow memory leak behaviour.

->INVALID ?

RSS indicates how many pages are currently in memory for Mozilla,
not Mozilla's working set and certainly not something as nebulous
as Mozilla's "memory usage".

Build ID: 2002082606 (1.0.1)
This happens on W2k too. IMHO, OS ->All.
1. Open mozilla
2. Open some tabs with any pages
3. See memory usage in Task Manager
4. Close all tabs
5. See memory usage again (the same number)
May be some hidden pref should be implemented to free memory used after closing tab?

P.S. Reporter, please provide build ID with your bugs.

It seems so.

>Please see my comment there.
The only thing I couldn't test was the memory reclaim on certain cases.
Other than that is seems to be the same bug.

Based on Comment #4 and Comment #5, I'm marking this as a dup of Bug #131456. If
anyone disagrees, please reopen, and explain why you think it isn't a dup.
