I can tell you this for sure: I don't need to start the app, only loading the
modules with their usual script is enough to shoot the box during heavy network
load.

At the moment I only have a partly decoded oops at hand where all the
vmware-modules symbols are missing (network action is Gig btw):


ksymoops 2.4.8 on i686 2.4.22-pre10.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.22-pre10/ (default)
     -m /boot/System.map-2.4.22-pre10 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.
