We are facing this issue where calls recording suddenly truncated without disconnecting the calls. CPU usage at that point in time sometimes well under 80%. 
      We are using ARI application to generate outbound calls. Two legs were bridged together and then Recorder/ARI channel used to record the audio in the bridge. Also recording happens directly in file in /var/spool/asterisk/recording/filename. Means not in temp file in temo directory. After looking into log files finds this.

Sophos anti-virs and TM Deep security agent are running on the server. So trying to figure out what cause this issue. Also need guidelines and help to further advance our investigation in right direction to locate/resolve the issue.
