the changelog keeps track of the changes applied to the database, a 
typical entry looks like:
dn: changenumber=4,cn=changelog
objectClass: top
objectClass: changelogentry
changeNumber: 4
targetDn: cn=tuser,ou=people,dc=example,dc=com
changeTime: 20140411093444Z
changeType: delete

each entry gets a DN made up from he changenumber, so your entries will 
be named:
....
dn: changenumber=61,cn=changelog
dn: changenumber=62,cn=changelog
dn: changenumber=63,cn=changelog
dn: changenumber=64,cn=changelog
....
changenumbers start and are always incremented, changelog trimming 
removes old entries (depending on config).

so if you do a search like:
ldapsearch .................. -b "cn=changelog"
the changenumber of the first entry rerurne should always increase, 
indicating that trimming works.

you said "thousands" of messages, how frequent are they really ?
