any suggestion?
BTW: we found the master-slaver synchronize transfer 40G+ every time:
seems like master - slaver synchronize full nodes's data ,not increnmental synchronzied
Hello @qingyuan18
Upgrading to the latest version is generally recommended. Also, please include the full crash report in the issue.
BTW: the following is from Redis' documentation
However if there is not enough backlog in the master buffers, or if the slave is referring to an history (replication ID) which is no longer known, than a full resynchronization happens: in this case the slave will get a full copy of the dataset, from scratch.
we have a redis 4.0.8 cluster with 3 master and 3 slavers , one or two of the slaver nodes alwasy crash during bgsave, the crash report as below:

the rdb.c:628 code shows there is no correct object type:
our data is zset with 18 lenth String and other simply String type:

can anyone help to locate which issue and how to fix it? so far I didn't see any client code's error ,do I need to upgrade the redis to 4.0.9?
any suggestion would be appreciated ! Thanks
