Linux 2.6.9 pktgen module causes INIT process respawning and sickness

From: Jeff V. Merkey

With pktgen.o configured to send 123MB/S on a gigabit on a system using pktgen set to the following parms:

pgset "odev eth1"
pgset "pkt_size 1500"
pgset "count 0"
pgset "ipg 5000"
pgset "src_min 10.0.0.1"
pgset "src_max 10.0.0.254"
pgset "dst_min 192.168.0.1"
pgset "dst_max 192.168.0.254"

After 37 hours of continual packet generation into a gigabit regeneration tap device,
the server system console will start to respawn the INIT process about every 10-12
hours of continuous packet generation.

As a side note, this module in Linux is extremely useful and the "USE WITH CAUTION" warnings
are certainly will stated. The performance of this tool is excellent.
