Hi together,
I updated my ipa servers last week.
Since then the primary master is running under heavy load. It look like that the ldap server reponsible for my domain is causing high I/O load. It's writing its logs over and over again.
Also the CPU is loaded:

Look at two following ls on the db directory.

All the apps are pretty slow with authentication.
The server is exclusivly running ipa.
Any ideas how I can proceed?
Thanks for you help.
Marc.
