prosody_mem memory usage - lacking dependency info?

[Bretos]

When updatating, getting memory usage info generates munin errors:

Quite the same here (Debian Jessie, Prosody 0.10).

same here, one of the commands used not working (any more?) with prosody 0.10

>for k,v in pairs(pposix.meminfo()) do print(k,v, '|') end
| Fatal error while running command, it did not complete

Same error on Debian stretch and Prosody 0.9.12-2.
The fix proposed by @hoedlmoser does not work for me.

[lemmy04]

same here. even with the patch above I still get:
(running on openSUSE Leap 42.3)

#8 (comment) works with Debian stretch and prosody 0.11.0
