Description of problem: if nsslapd-cachememsize set to the number larger than the RAM available, should result in proper error message. Steps to Reproduce: I tried giving a higher value of 1000GB to dn: cn=userRoot,cn=ldbm database,cn=plugins,cn=config's nsslapd-cachememsize from console, and the server crashed. Error :: >>> ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1) >>> < - deleted >>> > - added >>> 1,28d0 >>> < # extended LDIF >>> < # >>> < # LDAPv3 >>> < # base <cn=userRoot,cn=ldbm database,cn=plugins,cn=config> with >>> scope baseObject >>> < # filter: objectclass=* >>> < # requesting: ALL >>> < # >>> < >>> < # userRoot, ldbm database, plugins, config >>> < dn: cn=userRoot,cn=ldbm database,cn=plugins,cn=config >>> < objectClass: top >>> < objectClass: extensibleObject >>> < objectClass: nsBackendInstance >>> < cn: userRoot >>> < nsslapd-suffix: dc=example,dc=com >>> < nsslapd-cachesize: -1 >>> < nsslapd-cachememsize: 1073741824 >>> < nsslapd-readonly: off >>> < nsslapd-require-index: off >>> < nsslapd-directory: /var/lib/dirsrv/slapd-mgmt12/db/userRoot >>> < nsslapd-dncachememsize: 10485760 >>> < >>> < # search result >>> < search: 2 >>> < result: 0 Success >>> < >>> < # numResponses: 2 >>> < # numEntries: 1 >>> >>> ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1) >>> >>> >>> [root@mgmt12 scripts]# service dirsrv status >>> dirsrv mgmt12 dead but pid file exists >>> >>> [root@mgmt12 scripts]# tail -f /var/log/dirsrv/slapd-mgmt12/errors >>> [19/Mar/2013:07:22:31 -0400] memory allocator - calloc of 1 elems of >>> 268435664 bytes failed; OS error 12 (Cannot allocate memory) >>> The server has probably allocated all available virtual memory.

Actual results: Error message says :: "Can't contact LDAP server" Expected results: we should display a better error message on console which indicates that RAM is not enough.
