Summary:                    Record audio channels gets out of sync
Description: 
When recording with mixmonitor, some record files channels gets out of
sync.
The scenario was:
- Medium call traffic: More than 60 and less than 120 concurrent calls.
- All calls are recorded
- Codec: Alaw
- Record File format: WAV GSM
- Processor load: Never more than 50%
- Asterisk Version: 1.6.2.10 (also happened in older versions, since
1.4.19)
- SO Debian 5.0.3 - 2.6.26-2-686

Discovered that between the calls been ok and not ok my server performed a
ntpd remote time update;  been using ntpd on my server for a while, and
sync all my server/pc/Voip device clocks to the server.   Am wondering
whether altering the system time via the sec drifts, will affect timings
with asterisk.

Seen issues raised before with dates etc changing whilst asterisk is
running.

Are of you that are affected by this also use server NTPD remote
syncing/time updates ?
