- After running for a few days, my Linux system ends up with quite a
- few 'Zombie' processes. I can't kill them off, even with kill -9 and
- the only way to get rid of them is with a reboot. This is a typical
- 'ps -aux' screen after a few days.

- Notice that the processes are all 96k in size. The process number still
- shows up in the /proc partition, but I don't know how to get any info
- from that. I'm open to suggestions and advice.
-
- I'm running mostly SLS 0.98p5 with a 0.99p2 kernel, netbin0.1, X11, and
- smtp smail. The system also mounts and serves up NFS partitions.

- Thanks
