41205 - PSM threads consume 100% CPU forever after visiting above URL

Status: VERIFIED DUPLICATE of bug 34834

(Core :: Security: PSM, defect, P3)

Description

[Rickard Westman]

As soon as I go to https://www.ikanobanken.se/i_bank/, six psm threads/processes
are created, together consuming approximately 100% of the CPU.  If I immediately
press "Back" to return to a non-SSL page, the psm threads seem to remain
forever, consuming all of the CPU.  If I go further into the SSL-using site
(which requires a successful login) more threads are created, always consuming
close to 100% of the CPU together.  I have set the severity to "major", since
Mozilla is almost unusable when the pcm threads grab all available CPU power.

Interestingly, if I do a "strace -p" on one of the psm threads, strace exits
immediately and silently, and the thread disappears.  Repeating this, I can get
all psm threads to diseappear, reclaiming the CPU without having to exit or
crash Mozilla.

This bug is probably the same as #32605, although my configuration is different
(newer PSM, etc.)

This is using M15 binaries (Mozilla/5.0 (X11; U; Linux 2.2.14 i586; en-US; m15))
and the recommended PSM for those.

m15 is too old I am afraid - a lot has been fixed since m15

Verified.

I have now upgraded to M16 and the corresponding PSM.  The problem remains with
the exact same symptoms.

actually, I see this on m17 200061708 win98 kinda. The page loads very slow, and
does consume a lot of memory

I don't see this problem any more since I upgraded to M17 
(build 2000061408.)
