[Linux-cluster] nanny segfault problem

[Christopher Barry]

Greetings All,

running RHEL4U5

I have a bunch of services on my cluster w/ access via redundant
directors.

I've created a generic service checking script, which I'm specifying in
lvs.cf's 'send_program' config parameter.

script is attached to this post. see that for how it works with the
symlinks described below.

I create symlinks to the script for every service I want to check, with
their name containing the port to hit, as in:
/sbin/lvs-<port>.sh

so the symlink name to check ssh availability, for instance, is:
/sbin/lvs-22.sh

The script works fine, and returns the first contiguous block of
[[:alnum:]] text data from the connection attempt for use with the
expect line of lvs.cf.


The problem is, when nanny is spawned by pulse, all of the nanny
processes segfault.

this occurs almost instantly for every nanny process.

Can anyone venture a guess as to what is happening?
