pmie spawning more than 1 instance per host

[Jan-Frode Myklebust <janfrode@xxxxxxxxx>]

I'm using pmie to monitor about 50 hosts from a central monitor. The
central monitor is running the pmie_check from /etc/cron.hourly/, 
and annoyingly it seems to not always be able to detect if an instance
for a host is already running, so after a few days, I end up with more
than one pmie per host.

Anyone else seen this? And maybe have a workaround?

Running v2.7.1 on RHEL4 as the monitoring host, but saw the same 
problem on v2.5.0. Clients are a mix of mainly v2.5.0 and v2.7.1. All
RHEL4/RHEL5.
