I just upgraded to 2.4.8, and I experience a stability problem with synrepl and schema replication.
My replicas get cn=schema,cn=config through syncrepl. If the master is restarted, the replicas tend to crash (not always, but very frequently). The problem disapear if I don't replicate cn=schema,cn=config.
Below is a log of what happens at master restaty time, and the backtrace I collected in GDB. Any suggestion of what should I try next?
