Bug Description
Once in a while, a process called "ld-linux.so.2" starts consuming all my system resources, with CPU usage between 90-100%, my 2GB main memory AND my complete swap partition used up completely, making the system unresponsive to a degree that even single keystrokes need up to a minute to get interpreted by the system.
A forum post (http://
Two known workarounds:
1) uninstall package acroread
2) when slowdown starts, either 'killall -KILL ld-linux.so.2' (package 'lsb' not installed) or 'killall -KILL acroread' (package 'lsb' installed).
Affected Ubuntu version:

I have had the exact same problem since upgrading to 8.04.
Even worse, when the acroread (or ld-linux.so.2) has consumed all of the available system memory (after a significant amount of time), the whole computer locks (almost) completely with the harddisk LED flashing continuously. The systems responsiveness decreases to a minimal level with mouse pointer movements daking several seconds.
When I kill the X-server (and thus acroread) via Ctrl-Alt-Backspace (sometimes taking several minutes), the system works as before the crash.
I've reproduced this bug multiple times; it always coincides with the Adobe Reader Firefox plugin crashing out of Firefox and Opera web browser.
I would consider this a CRITICAL BUG for a LTS distribution version, because:
1. The associated whole-system-crash occurs sporadic and is
2. delayed, can't easily be associated with the crashed application and
3. causes data loss because it forces unknowing users to reboot their system.
I'm Using Kubuntu 8.04 AMD 64 with a vanilla Linux 2.6.27 kernel, but I've had this bug with several other kernel versions before.
