Extract of error log showing CoS cache rebuilds

CoS template for user-type descripton and user classes list (relevant attributes only)

We are still missing the COS templates mentioned in the cos definitions ldif file you provided:

{{{
ou=Departments,ou=Tables,dc=brighton,dc=ac,dc=uk
ou=Buildings,ou=Tables,dc=brighton,dc=ac,dc=uk
ou=Courses,ou=Tables,dc=brighton,dc=ac,dc=uk
ou=StaffTypes,ou=Tables,dc=brighton,dc=ac,dc=uk
ou=OperatorTypes,ou=Tables,dc=brighton,dc=ac,dc=uk
ou=StatusCodes,ou=Tables,dc=brighton,dc=ac,dc=uk
}}}

Sorry for the delay, Mark - now attached. I've only included minimally relevant attributes and a single example of each (the ones which match the example 'st8' user account).
Do let me know if you need any more of the structure - and whether you'd like me to test anything else or build a clearer test case...

Thanks (and much appreciated!),
Steve

One thing I'd forgotten to mention: a quick test of the problem is how quickly the ''dirsrv'' service starts/restarts/stops. On my server, it takes well over a minute for any of these operations, whilst the CoS cache rebuilds.

(Do let me know if more info/test cases would be helpful...)

Unfortunately I can not reproduce the cos cache being rebuild by updating a non-cos attribute on 1.2.11.

[1] I created dc=brighton,dc=ac,dc=uk
[2] I added all the provided LDIFs, although you are still missing two:

[17/Apr/2014:10:17:49 -0400] - Skipping CoS Definition cn=cosFacultyDescription,ou=People,dc=brighton,dc=ac,dc=uk--no CoS Templates found, which should be added before the CoS Definition.
[17/Apr/2014:10:17:49 -0400] - Skipping CoS Definition cn=cosEduPersonAffiliation,ou=People,dc=brighton,dc=ac,dc=uk--no CoS Templates found, which should be added before the CoS Definition.

[3] I added the st8 user, and then I added 200K users(just like st8) to ou=people,dc=brighton,dc=ac,dc=uk. They all correctly return cos attributes/values

[4] I can update the same entry over and over, different entries, etc, but the cos cache does not rebuild, and performance is fine.

Obviously something is missing from my testcase. Maybe you could follow my exact steps in your environment - basically starting over. I'm attaching my ldif from my setup, maybe you can see if you can use it to reproduce your issue.
