Indeed : my current bash version is 4.3.11
Although I don't have line 585 in my fancontrol script
I can apply the the patch (lines 497 & 536 for fancontrol v0.7)

I also gave it a try without the wait lines and not sending to
background the previous
sleep command the wait was waiting for anyway (useless ?)

=> Mem consumption seems to be the same in all cases, we'll see in the
long run...
BTW, can you please tell me
* Which architecture this is (x86 or x86-64)?
* The value of "ulimit -u" on this system.
* The total amount of memory on the system.

As Chet Ramey explained to me, the memory consumption is bound and the
default limit depends on these factors. Assuming an x86-64 system,
eating 22 MB of memory as you reported would take about 734000 records
of 32 bytes each, and "ulimit -u" would be set to that value by default
for a system with about 187 GB of memory. Which I would not expect in a
NAS, so something is wrong.


The hardware is actually a ReadyNAS ultra 6000 with 2GB RAM.
I'm running a x86_64 ubuntu server 14.04 with 3.16 SMP kernel
and fancontrol from standard repos (pkg vers is 1:3.3.4-2ubuntu1).
