Bug 243908

Description of problem:

Nanny is blocking SIGALRM and some other process signals.  I'm trying to monitor
 tftp and the tftp client times out with a SIGALRM, thus leaving the tftp
process to hang around forever never going away.

The tftp client never terminates, nanny never gets a bad status and never
removes the server from the cluster.

Version-Release number of selected component (if applicable):


How reproducible:

Every Time

Steps to Reproduce:
1. Configure Piranha to use this nagios check_tftp plugin:
http://mathias-kettner.de/download/check_tftp
2. Stop xinetd and in.tftpd on the server
3. Watch the tftp process hang forever.

lvs.cf
expect = "OK - answer from server"
use_regex = 0
send_program = "/usr/local/bin/check_tftp --connect %h"

Actual results:
# date
Tue Jun 12 13:35:32 EDT 2007

root     13206  ... Ts   12:19   0:00 /usr/sbin/nanny -c -h 10.0.0.4 -p 69 -f 1
-u -e /usr/local/bin/check_tftp --connect %h -x OK - answer from server -q -a 15
-I /sbin/ipvsadm -t 6 -w 1 -V 10.98.200.114 -M g -U none --lvs
root     17482  ... S    12:19   0:00 tftp 10.0.0.4
root     17483  ... S    12:19   0:00 head -n 1

Expected results:

tftp to actually terminate, and the check_tftp script to return an error output
for nanny to parse.
