Hi,
We have a FreeIPA 4.1.4 setup on F21 servers. There is 1 master and 7
replicas in different regions. Earlier there was only 1 replica. Since I
added new replicas, on the master node, once in a while the kerberos
process dumps core and everything stops working - authentication,
replication etc. If we restart everything using "ipactl restart" things are
back to normal.
Attached is the output from journalctl for kerberos.
Has anyone come across this ? Are there any pointers to troubleshooting
this ?
Any help is appreciated.
Thanks.
