Call-Recording skips after few minutes in few calls only

Hi All,
I have installed Vicidial 2.14-617a with Asterisk 1.8 and MySql 5.7.
Everything works fine except below issue.
In my few inbound calls the recording is getting skipped after few minutes.
My call was running for 6 minutes but in recording file (/var/spool/asterisk/monitorDONE/GSM/) it is gets recorded from 00:00 to 03:15 (Around 3 minutes from beginning) duration.
How to resolve this? This gets affected for few calls only.
Any help will be great for me to understand the Issue.
Regards,
Jayesh
