Thanks for the reply and the link Rich!

dbmon.sh is a handy tool indeed.

I read the instructions and upped my entry cache size to 2gb because I have enough ram.
Everything went well until
|service dirsrv restart

|Oddly enough everything appears to be working. Are these messages safe to 
ignore?

This is definitely not related to the cache size.

|Not sure what the problem is - looks like something has done an override of the standard schema definition of dc. http://tools.ietf.org/html/rfc4519 defines it with syntax 1.3.6.1.4.1.1466.115.121.1.26.

rpm -q 389-ds-base

find /etc/dirsrv -name \*.ldif -exec grep 0.9.2342.19200300.100.1.25 {} /dev/null \;

|Another run of dbmon.sh shows that my entry cache was increased.

Thanks again Rich,
I have been having an abundance of issues with my FreeIPA server lately. I'm not surprised that error is not related. I was not sure as It has not surfaced in my logs before I changed the entry cache size. Possibly this will be the clue to get me on the road to recovery.

I migrated from OpenLdap about a year ago. So my install is a migration. I also recently tried to add a replica. Which prompted me to update the schema on the master before it would replicate.

What exactly did you do? You should not have migrated the standard schema from openldap. Did you have to override the definition of 'dc' for some reason?

This definition is wrong. Both RFC 2247 and RFC 4519 define 'dc' as syntax 1.3.6.1.4.1.1466.115.121.1.26 - that is, 7-bit ASCII only. Do you have some application that requires 8-bit or unicode characters (syntax 1.3.6.1.4.1.1466.115.121.1.15) in domain component names? If it is absolutely required that dc accepts unicode, then you'll have to change the matching rules as well, to be unicode compatible: EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch - that is, just get rid of the IA5.


/etc/dirsrv/schema/00core.ldif:attributeTypes: ( 0.9.2342.19200300.100.1.25 NAME ( 'dc' 'domaincomponent' ) /etc/dirsrv/slapd-CS-OBERLIN-EDU/schema.bak/00core.ldif:attributeTypes: ( 0.9.2342.19200300.100.1.25 NAME ( 'dc' 'domaincomponent' ) /etc/dirsrv/slapd-CS-OBERLIN-EDU/schema/00core.ldif:attributeTypes: ( 0.9.2342.19200300.100.1.25 NAME ( 'dc' 'domaincomponent' )
