Thanks for all you input. 
Trying the ldapsearch with -E pr(paged result) command gives the same
error

DB2-95-02:~ # ldapsearch -E '!pr=10' -x -h 10.217.94.154 -b
"dc=openldap,dc=dev,dc=net6,dc=com" -s sub '(objectclass=person)' dn

Seems like we use ldbm database. Does it support paged result in the
version we use (2.3.19)? If not, is it supported in a later version?

Thanks,

Actually, you should use -E '!pr=10'; the '!' means "critical".  This 
would reproduce the exact condition that triggered the error you
noticed.
