[collectd] Collectd clients will loose connection to collectd server if restarted

[Giorgio Mandolfo]

Hi all,

First of all a brief 'thank you' to everyone that contributed to this 
great piece of software.

I'm currently using collectd to monitor a small number of hosts. I have 
a collected set as in server mode listening in the office and around 30 
hosts are running collectd and sending (through an IPSec VPN) data 
collected.

Graphs are then displayed locally on the server.

What happens is that if for any reason collectd running on the server 
restarts (let's just say, reboot, power failure, hardware upgrade), all 
the collectd daemons running on the 30 clients still continue sending 
data (I can see it with tcpdump), but the collectd server seems not 
catching it. After restarting collectd on every client, the server 
starts to collect data again.

You probably understand that if I every time I need to restart collectd 
on the server it's going to be a hassle to restart all the 30 (and 
counting) collectd processing on 30 different machines :)

Does anybody had the same problem? What am I missing here?

Thanks in advance,

Giorgio
