230618 - RAM cache doesn't seem to clean up during long sessions

Status: RESOLVED FIXED

(SeaMonkey :: General, defect)

User-Agent:       Mozilla/5.0 (OS/2; U; Warp 4.5; en-US; rv:1.6b) Gecko/20031209
Build Identifier: Mozilla/5.0 (OS/2; U; Warp 4.5; en-US; rv:1.6b) Gecko/20031209

After browsing for a very long time, particularly when viewing large graphics, I
notice that RAM cache continues to grow without ever purging older objects.
Eventually, Mozilla closes on its own, but does not place entry in POPUPLOG.OS2,
which implies it exceeded the 512MB(?) limit....

Reproducible: Always

Steps to Reproduce:
1. Browse, for instance, MapQuest, starting at some position in Los Angeles,
large map size.
2. Move east several hundred times.


Actual Results:  
Works fine until it doesn't. Eventually, Mozilla will just close. SWAPPER.DAT is
very large at this point.

Expected Results:  
Kept moving east.

Probably OS/2-specific.

Attachment: Fix for problem where we don't get a disk cache

I'm going to take a stab at this one.

Those mapquest images aren't supposed to be in the RAM cache.

We have a bug where intermittently, OS/2 Mozilla doesn't get a disk cache and
memory cache can get out of control because everything gets put there.

This is a fix for that problem.

Fix checked in.

I hope this takes care of it.

I gave 1.7rc1 a good workout -- viewing about 35MB of images -- and cache
management is much improved; possibly fixed. My swap file grew 8MB for some
reason toward the end of a *long* browser session, but that is most likely
interaction with WarpVision. 

WFM as far as I'm concerned. Thanks!
