[Freeipa-users] Sudden replication failure

[Burke Rosen]

Hello,

I'm running two replicated freeIPA servers. One of them spontaneously 
failed. After taking the misbehaving server down, the remaining 
replicant handled everything fine. I restored the system to its original 
working state by uninstalling ipa-server from the non-functional server 
and re-replicating from the working server. All is well, but I am trying 
to figure out what might have caused the problem in the first place. 
Below are first few (presumably) relevant lines of the the error log. 
Can someone help me interpret them?

Thank you,

-Burke Rosen
