Asterisk 11.2.1 Realtime - rtcachefriends problem , no cache

Hi all
Before post this topic ,i searched and couldnt find anything about it. i have Asterisk 11.2.1 X64 and it is realtime on mysql. everything going right but cache friends.
when a peer registered and it can be shown on CLI and peers table. but after sip.conf is reloaded , cached information’s gone.
sip.conf

rtcachefriends =yes ;rtsavesysname=yes rtautoclear=no qualify=no ;rtupdate=yes
and more default attributes.
my users info is here

after reload my sip.conf it gave “no such a 1001” . it is waiting for re-registry . So it is really big trouble when we trying to solve a problem , Because firstly we need to learn “user is registered?”

if anyone help me about it , i will be very happy
Thanks

You can use the “sip show peer load” in order to reload immediately and don’t wait for a re-registration

Thanks for reply , it is a solution .
i think it is a bug in Asterisk 11.2.1
