SIGHUP reaction of Nrpe 2.14 on Aix 6.1

[Michal Fiala]

Hallo,

We are running nrpe 2.14 on Aix 6.1. We have a wrong behaviour in
reaction of HUP signal. First HUP is OK, second HUP causes nrpe
termination. Details see below. Please what could be wrong?

Thanks

Michal Fiala

First attempt is OK, ends with restarting nrpe

# ps -U probes -o pid,start,args
     PID  STARTED COMMAND
16122000 14:05:53 /usr/local/nagios/bin/nrpe -c /etc/nagios/nrpe.cfg -d -s

# kill -HUP `cat /var/run/nagios/nrpe.pid`

# tail /var/log/syslog
Aug 14 14:07:59 r4238 daemon:notice nrpe[16122000]: Caught SIGHUP -

     PID  STARTED COMMAND
16122000 14:05:53 /usr/local/nagios/bin/nrpe -c /etc/nagios/nrpe.cfg -d -s

Second attempt ends with terminating nrpe

# ps -U probes -o pid,start,args
     PID  STARTED COMMAND
16122000 14:05:53 /usr/local/nagios/bin/nrpe -c /etc/nagios/nrpe.cfg -d -s

# kill -HUP `cat /var/run/nagios/nrpe.pid`

There is no records in syslog after HUP signal, nrpe is not running. SRC
started new instance of nrpe, so I can see in syslog

# tail /var/log/syslog
