- Do you have the filesystems mounted "soft"? If the server is
- heavily loaded and an NFS request times out it'll give a write error
- on "soft" mounts, rather than retrying. If that error happens to be
- a page of an executable that's being paged from the text image, you
- will get a "swap error" and it'll kill the process.
