Hi Stefan,

Thank you for helping.

/usr/bin/rrdcached -P UPDATE,HELP,STATS,QUIT -l 
unix:/var/run/rrdcached.sock -w 420 -t 10 -s 33 -z 200 -j <long dir> -F

I tried to set $record as "N:$in:$out" and removed that "--template" 
stuff. No erros anymore. It worked!

But now only journal files are being written, and rrd files are not.

As far as I can tell, permissions are all correctly set.
Socket is writable by the user that runs RRD perl modules, the rrd files 
owner is ok. Only journal files belong to root.

I tried to flushall, but nothing happened.
Journals sizes keep growing up and when timeout (-w 420) comes, it 
shrinks and starts all over.

But rrd files stay untouched.

Any ideas?
