Dear all,

I have 4 servers with version 2.4.9 configured into 4 way masters, the name of the servers are disb01 (SID:001), disb02 (SID:002), pisb01 (SID:003) and pisb02 (SID:004). Attached is the config file for the 4 servers.

All the 4 servers are configured and started on Oct 29 night. At that time, I test the data synchronization, the result is positive. However, today, customer reported that data synchronization occurs, then, I perform the following simple test and find that data is really can't replicated.

- When I added a record (the key is 20081104105123.573091Z#000000#003#000000) in pisb01, the data can be replicated to pisb02, but the other 2 servers disb01 and disb02 cannot find this record. The log in disb01 and disb02 indicates that the CSN is too old.

- When I added a record (the key is 20081104105455.436768Z#000000#001#000000) in disb01, the data can be replicated to pisb01, but the other 2 servers disb02 and pisb02 cannot find this record. The log in disb01 and disb02 indicates that the CSN is too old.

The log for the 4 servers is attached...

Any possible reasons for this error "CSN too old" ? I find from the log that seems all servers received update at the same time (up to seconds, no millisecond is shown in the log)

Thanks
