Hi Serghei, =A0 =A0=A0=A0=A0 For the first point, the function ldap_msgfree=A0 will check f= or NULL, so if the check is missing, no error occurs. =A0 =A0=A0=A0 I am using the ldap_search_ext_s function (the synchronous one) s= o the second and third point doesn't apply as i don't have access to the ms= gid. If the memory leak is high maybe will switch to the async queries. =A0 Regards, Alin =A0 =A0=A0=20 =A0=A0=A0=20

Buna ziua, domnule.
1. The pointer must be checked before operation, e.g. if (res !=3D NULL) { =A0 =A0 ldap_msgfree (res); =A0 =A0 res =3D NULL; }
2. Also while processing the ext query, you should call the functions in the following manner: 2.1 ldap_search_ext() which has pointer to msgid 2.2 ldap_result() which gives the LDAPMessage structure for the msgid 2.3 if ok - ldap_parse_result() 2.4 on any stage if something is not good and you have the msgid filled with value (integer, typicaly more then 1) you should call ldap_abandon_ext() for that msgid 2.5 Finish with ldap_msgfree()
3. Periodically between the asynchronous searches (after 100 for example)you should call ldap_result() with short timer and LDAP_RES_ANY argue for clearing stalled or nonfreed calls. The obtained LDAPMessage can be freed with ldap_msgfree(). Of course, you can count the asynch calls which hadn't been completed or were timed out and you can make the corresponding cycle for checking all iterations.
Please try and let me know.
With respect, Serghei.
