BUG REPORT: slapd defunct/zombie

Hi there,

Since I couldn't find any information regarding this problem anywhere, I'd
better report it as a bug.

My slapd, OpenLDAP 1.2.1 but also 1.2.0, compiled with linuxthreads-0.71,
irregularly but rather often just stops, when I do a 'ps ax | grep slapd'
I see this:

  137 ?        S      0:00 /usr/local/libexec/slapd
  153 ?        Z      0:00 [slapd <defunct>]
  154 ?        S      0:00 /usr/local/libexec/slapd

Sometimes it's 'zombie' instead of 'defunct'. I then have to kill -9
<first process> and start slapd again. Nothing gets damaged.

Output of that very useful script (for system info) from the Linux kernel
tree, ver_linux, says:

-- Versions installed: (if some fields are empty or looks
-- unusual then possibly you have very old versions)

The problem has also appeared on other 2.2.x kernels, 2.0.x not tested.

I'd be happy to provide any info you need, of course.
