Realtime Asterisk sip reload disconnects call

Hi everyone ,I am using Realtime Asterisk .To show all the peers in sip show peers command
I have use rtcachefriend=yes in sip general setting. Due to this whenever i do sip reload ,all call disconnected automatically. When i remove rtcachefriend=yes from general setting , it works perfectly.

Please help me to solve this problem.
I am using Realiance SIP trunk as Media for call.
