i have strange problem with asterisk 13 mixmonitor, recording to wav
when the system is under load, there are sometimes missing syllable
there arent BIG spikes on cpus recordings are to ramdisk (/dev/shm)
First, try recording to a real disk (preferrably a separate drive, so nothing else will be seeking the heads about; and connected by SATA, not USB, for full speed). Does that work any better?

i tried before. IO is not the problem
Are you saying that it records fine when you use a real disk, but not with a ramdisk?
And why are you using a ramdisk for your mixmonitor recordings?

i have problem in both scenarios im using ramdisk because is faster and IO cannot be problem
when you say load – how many concurrent calls? Is there transcoding happening? sip / PRIs ? what load?
Dne 28.1.2016 v 13:37 Brian :: napsal(a):
12 concurrent calls
under 1.5 with 4x 1Ghz vcpus (its vmware VPS)
12 calls isn’t under any type of load.
Someone with better understanding of Asterisk internals may chime in here.
Could it be vmware timing? Is timing critical when using mixmonitor?
I’ve seen > 100 concurrent calls being recorded wtihout issue.
