there arent BIG spikes on cpus
recordings are to ramdisk (/dev/shm)

any hints?

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?

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?

when you say load - how many concurrent calls? Is there transcoding happening? sip / PRIs ? what load?

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.
