Barry Oglesby commented on GEODE-3718:
--------------------------------------
Lynn and I have a test that reproduces this issue.
3 servers configured like:
server 1 - replicate region
server 2 - replicate persistent region
server 3 - replicate persistent region
Server 1 is configured like:
```
<cache ...>
<cache-server port="0"/>
<region name="UTLatest" refid="REPLICATE"/>
</cache>
```
Servers 2 and 3 are configured like:
```
<cache ...>
<cache-server port="0"/>
<region name="UTLatest" refid="REPLICATE_PERSISTENT"/>
</cache>
```
This matches the customer's proxy and data groups members. Server1 is in the
proxy group and servers 2 and 3 are in the data group.
Note: You must start the persistent servers first.
kill -9 one of the servers with a replicate persistent region.
When synchronization occurs (after maximumTimeBetweenPings - 60000ms), a
message like this will be logged in each member:
[info 2019/06/24 09:46:13.133 PDT <Timer-2> tid=0x2b] Region UTLatest is
requesting synchronization with 192.168.1.2(server3:51729)<ec><v20>:41002 for
192.168.1.2(server2:51722)<ec><v19>:41001
The member with the replicate region will also throw the ToDataException.
A couple work-arounds are:
- Instead of using a replicate region in server1, use a replicate proxy region
- Use replicate persistent regions in all members
