mozilla-1.0.1_1,2
flashplugin-mozilla-0.4.10_1
>Description:
When mozilla starts the flash-plugin, the plugin creates a SysV
shared memory block (SHM) to communicate with the browser. This
SHM is not removed when the plugin is closed, so SHM Blocks accumulate
until the machine runs out of available SHM slots. Check with ipcs -m
>How-To-Repeat:
View any webpage using the flashplugin, like e.g. the articles linked
to www.heise.de/tp/ (these use a flash navigation menu). Check your
existing SHM blocks before and after with "ipcs -m"
>Fix:
The atached patch for plugin.c fixes the problem for me.
