1005831 - Allocates almost all memory and used almost 100% cpu and getting freeze, finally crash

Status: RESOLVED INCOMPLETE

(Core :: General, defect)

Description

[gene0mega]

Attachment: Yes, this is the page BUG occurs. The script error(Permission Denied) occur @ open(K_PATH_BACKUP)

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:24.0) Gecko/20100101 Firefox/24.0 (Beta/Release)
Build ID: 20140319075056

Steps to reproduce:

1. Setup a PHP server
2. Set the max_execution_time to a high value(even 45 works in my example)
3. Write a piece of code generate xhtml, but have some none-fatal error among it(like permission denied)
4. Let FF24.4 ESR access it.


Actual results:

As what It acts (in my example)
Part of page's content(which script error not occur) is loaded,
and the page seems keep loading(know it from the tab's running circle),
and it's getting laggy and cpu had run upto almost 100%,
and the Load Average went upto above 1(2 core, 4 threads CPU),
then looking in the `top`,
you will notice it increasingly allocate memory for FF24.4(upto about 60% of 4G),
occasionally it will crash,
or sometimes it stop loading itself and keep sane



Expected results:

Keeping sane when server ``ignoring'' him during communication is alive(avoiding eating up the memory)
