Hello,
Need some more information here:

The Asterisk server is a Dell PowerEdge 6850 with the following specs.
Please note that we are NOT recording to the hard drive. We are
recording to a RAM disk as detailed here
What codec are the calls? What codec are you recording in?
I would try some non-Dell hardware, I would also try a less bloated
Linux Distro, something like Slackware, just to see if that had any
effect. And make sure you use the megaraid2 linux drivers.

Matt,
The calls are u-Law. The format of the recordings is PCM. Is this
correct to prevent transcoding the recording? We've noloaded all other
codecs, so I don't believe that transcoding is occurring. I've only
ever seen "show translation" generate the following output:

Hello,
To see if it's somehow the recording throughput that's the problem I'd
suggest trying recording in GSM just as a test and see how that is.
As for the hardware, just try a machine with no Dell parts in it. I've
talked to many Asterisk users who's problems went away when they
switched to
List users,
I've traced the writing of the leg files to two functions in channel.c:
ast_write()
ast_read()
They both contain similar code, so I'm going to limit my analysis to one
of them. If I'm misunderstanding anything or am flat out wrong, please
don't hesitate to correct me. Your input
Matt,
I have a similar issue to the 'Skips and Pops' with the On Hold
music on my Ast 1.2.1 box. I've tried moving stuff to a RAM Disk, yet I
still get reports from agents that callers report that the 'music on
hold sounds horrible'.
It has squeaks and pops.. kind of like digital
List users,
I'm using the Monitor application to record calls. Most of the
recordings are audible, but contain skips accompanied by a popping
sound. Sometimes they are isolated, sometimes they appear in groups.
Call quality is excellent and seems unaffected by whatever is causing
this
Hello,

- how many recordings at once
In my experience, HyperThreading does not
