 Workaround (if any):

with pmap(Process mapping), I found there is memory leak
[code]
pmap 5304 <- firefox pid

5304: /usr/lib/firefox-3.0.11/firefox --display=:0
08048000 28K r-x-- /usr/lib/firefox-3.0.11/firefox

.... hundreds line of /usr/share/fonts/truetype/LexiGulim090423.ttf
[/code]

and it increase very quick

If I set English or japanese locale, there is only one (One time load) /usr/share/fonts/truetype/LexiGulim090423.ttf

Font name is setup by /etc/fonts/conf.d/69-language-selector-ko-kr.conf
I try to change font to other korean fonts, or English fonts, etc but firefox is crased

So I launch firefox with debugger, and at crash point, there is many threads

Thank you for reporting this to Ubuntu. I can confirm the memory leak, but I have locales purged on my machine. Could you please run the following from the command line and attach /tmp/strace_ff.log after the crash occurs:
strace -eopen firefox 2>&1 | tee /tmp/strace_ff.log

[Micah Gersten (micahg)]

Also, please let us know which OS you ran the test on.
Thanks.

[Jisung, Ahn (narusas)]

I test on xubuntu 9.04 clean installation with Intel D949GSEJT(ATOM Board)

[Jisung, Ahn (narusas)]

And kubuntu 9.04

[Micah Gersten (micahg)]

Thank you for the straces. It seems like you may be missing the Korean fonts. Could you please post the results of:
apt-cache policy ttf-unfonts-core

[Micah Gersten (micahg)]

My apologies, please disregard the last message. The fonts were not an issue in either case.

[cocoon (sckang0722)]

Plz, test this site.
