>Description:
On extremely high (i.e. testing/benchmarking) loads of HTTP traffic,
the system will crash with errors of "Out of memory buffers". This
occurs at load levels tolerable by Linux, etc.
CPU load at crash is unremarkable (~0.6).
>How-To-Repeat:
Direct HTTP traffic at high levels (up to and exceeding 6Mbits/sec) to
the server, using WebPest or similar.
