Hi all,
I'm using fancontrol on a NetGear ReadyNAS Ultra 6000 (X86 arch) using
ubuntu server 14 and it's great !
But as you may see in the forward (or not : I don't know if the pic will
be filtered...), fancontrol
memory usage, although not huge, is worryingly increasing as uptime goes on.
From 6 Mb at the moment I start the daemon to 27 Mb less than a week
later, and still growing !
Here are few system stats, I think pinpointed the issue, but that's all
I could do...
pmap -x FANCONTROL_PID (see 25 Mb in dirty column)

Look like it's the heap ( memory leak in the fancontrol shell script !? )
cat /proc/FANCONTROL_PID/io

write_bytes: 0

It looks like every data read by the process is kept in memory (pwm
sensors data ?) : It doesn't seems OK to me...
Am I wrong ? Do someone have any clue or suggestion ?
Thanks,
Cédric L.M.

Sorry I don't maintain fancontrol any more, please check the lm_sensors
project mailinglist, those guys might be able to help.
Best regards
Marius

Hi Marius,
First : Thanks for fancontrol (I suppose... I foud your mail in the
man page). :-)
As you can see on following graph fancontrol is consuming more and
more memory
as its uptime goes : almost 6 times more than when it started up
less than a week ago...
Got any information related to that ?
( will it stops growing once a certain level is reached, is it
threatening for my system/fancontrol daemon ...)
Thanks,
Cédric L.M.
