Stress test parameters are as follows.

TPS : 1000
Users in LDAP DB : 50K
LDAP operation performed during stress : ldapsearch.

Problem is, user is fetched from LDAP server(verified this with tcpdump), but ldap_get_values returns 'DECODING ERROR'.
This happens randomly during stress for 8 or 9 users out of 50K, during stress. 
If ldap search is performed for a single user, there is no issue.

Is this a known issue in OpenLDAP client library ? Is any fix available for this issue.
