Description

We saw this problem recently on several instances. The symptoms are:

  • Continuous reg-generation, and everything else (UI/API/etc.) is slow
  • high wait on the system
  • when looker closer, the slapd process makes a very high volume of reads

This is fixed by a restart of the slapd (and rudder-jetty) services, but happens again later.

It seems to regularly trigger at 0:00, maybe because of the daily inventory update.

Seen at least on 6.2.10.

It's related to a lack of memory available for the system cache, so the ldap needs to look on drive rather than using cache
We could improve this situation by being less reliant on ldap for most common actions
