Views Problem

Hello,

- Using Bind 9.2.1 on Solaris 8,
- 2 Masters,  2 Slaves
- 3 views (internal, external, ext-chaos CHAOS)

When i reload zones on the name servers, how should i proceed?
1. copy zone file testzone.zone to the two masters
2. "rndc reload testzone.ch in internal" --- on masters
    (slave should get notification and update, which works)
3. "rndc reload testzone.ch in external" --- on masters
    (slave should get notification and update, which works only sometimes)
4. do I need to "rndc reload testzone.ch in internal" resp. "rndc reload 
testzone.ch in external"
    on the slaves as well?
    Or use "rndc refresh testzone.ch in internal" and "rndc refresh 
testzone.ch in external" on
    the slaves?
    Whatever I do on the slaves, the updates won't work all the times.
    Sometimes the slaves transfer the internal view and save it in the 
extenal view.

Is this a known problem???
Example:
1. Update serial on external view of testzone.zone and copy to master
2. "rndc reload testzone.ch in external"
In the log file I see
Aug 26 19:35:35.104 general: info: zone testzone.ch/IN: loaded serial 
2002082802
Aug 26 19:35:47.505 general: info: zone testzone.ch/IN: loaded serial 
2002082802
(reloaded twice)
but no zone transfer from a slave

3. one the slave do first "rndc reload testzone.ch in external" but no 
zone transfer.
    After a while i try "rndc refresh testzone.ch in external" but 
nothing again.
   


I could write a test script and try tomorrow.
