I'm still trying to figure out why my servers sometimes get into a state where queries requesting the memberOf attribute take an exceedingly long time to process, for example:
When the server gets like this, there's a very high read IO load, 200-300Mb/s, compared to generally less than 1Mb/s when things are working right.
It almost seems like it's doing a full disk scan searching for members every time.
Any suggestions on what to dig into?
How large is the total size of all mdb databases? How much RAM do you have on the system? Is it possible that you've exceeded the index slot size?
