DB2 LDAP Crash On Linux
Body
Hello All,
When DB2 crashes or hangs of it usually causes DB2 to create a trap that leads up to the failure, in this case the trap usually happens out side of DB2 and shows the following:
If the call stack shows the following:
0x00002AAACE1F49CF _nss_ldap_ent_context_release + 0x002f (/lib64/libnss_ldap.so.2)
0x00002AAACE1F6A75 _nss_ldap_endgrent + 0x0015 (/lib64/libnss_ldap.so.2)
Or if your OS logs found /var/log/messages show:
May 7 08:23:33 db2test db2sysc 0[11696]: nss_ldap: could not get LDAP result - Can't contact LDAP server
May 7 08:23:37 db2test db2pd: nss-ldap: do_open: do_start_tls failed:stat=-1
May 7 08:23:38 db2test db2pd: nss_ldap: reconnected to LDAP server ldap://db2test.ca.db2test1.com/
