153025 - freeze on linuxtoday.org when fetching something from ad.doubleclick.net

Status: VERIFIED WORKSFORME

(SeaMonkey :: General, defect)

Description

[Terry Griffin]

There's something on http://linuxtoday.org/ this evening (June 19,10PM,PST)
that's freezing Mozilla 1.0. The last thing it says before it locks up is that
it's fetching something from ad.doubleclick.net.

I did an strace on some mozilla-bin threads to see what they were doing.
The ps command showed this:

 3703 ?        S      0:05 /usr/lib/mozilla-1.0.0/mozilla-bin
 3716 ?        S      0:00 /usr/lib/mozilla-1.0.0/mozilla-bin
 3717 ?        S      0:00 /usr/lib/mozilla-1.0.0/mozilla-bin
 3718 ?        S      0:00 /usr/lib/mozilla-1.0.0/mozilla-bin
 3719 ?        S      0:00 /usr/lib/mozilla-1.0.0/mozilla-bin
 3720 ?        S      0:00 /usr/lib/mozilla-1.0.0/mozilla-bin

strace showed 3703 looping on poll(), 3716 looping on getppid()
and poll(), 3717 looping on gettimeofday() and poll(), and 3718
through 3720 were making no system calls. %CPU utilization was
zero for all threads as indicated by top. It took some kill -9s
to clean up.

Make that 10PM PDT (not PST), or 05:00 GMT on June 20 if you prefer.

worksforme with linux trunk build 20020619 and 1.0 release.

Whatever is was on the site that was triggering the problem is gone now. I can't repeat the freeze.

It's back, 3:05 PM PST, Sunday June 23.

I notice when this happens that I have a defunct java_vm process. It
seems to be one of the advertisements on the left side that's doing
it. Using Netscape 4.79 I found these ads playing today:

- An HP advertisement
- Two different Oracle advertisements, one for 9i JDeveloper and
one for 9i Application Server.
- A small Linux International sponsoring member reminder.

Returning to Mozilla and continually reloading, I was unable to duplicate
the problem again, but all I could get was the two Oracle ads leading
me to believe that it was one of the other ads that was the trigger.

[Kai Lahmann (is there, where MNG is)]

reporter (Terry Griffin): can you reproduce this bug with a recent build of
mozilla (for example, 1.1beta)? if so, please comment again with details. if
not, please resolve this bug as WORKSFORME. thanks.

I've not seen it for many weeks, even with 1.0. The problem was triggered
by some banner ad which linuxtoday is no longer running. I never pinned
down exactly which ad because Mozilla would freeze before displaying any
portion of the banners.

I'll go ahead and change the status until it comes back.

I guess the flash-hang (58~ something)
