I've got caught in pmlogger stampede after using the following
incantation in the control file:
# special local logger
localhost n n PCP_LOG_DIR/pmlogger/mumble -c
pmlogger was started with -h localhost argument which was helpfully
replaced in the map file with the actual host name, that host name did
not match what pmlogger_check and pmlogger_daily were expecting,
pmlogger_check went troppo and started starting new logger every time
it was invoked, pmlogger_daily tried to merge archives which were
still written by the horde of pmlogger - it wasn't thrilled by that.
The reason I've used 'localhost' instead of LOCALHOSTNAME was because
on that machine's name is not resolvable: it's not in DNS and it's not
in the /etc/hosts (DHCP addresses and generic hostnames).
I've added the following in pmlogger_check

which pmlogger does.
