[Samba] samba crashes losing all machine a/c's

[mallapadi niranjan]

Hi all

I have been using samba 3.0.21 with openldap , and facing some problems.
since i am using samba with openldap, samba hangs  abruptly,
I have tuned openldap with DB_CONFIG parameters
my DB_CONFIG file is as follows
#########################################

set_cachesize           0 150000000 1
set_lg_regionmax        262144
set_lg_bsize            2097152
#set_lg_dir             /var/log/bdb
set_flags               DB_LOG_AUTOREMOVE
#########################################

but after i do db_recover and start my ldap and samba, i have to rejoin all
my clients system to PDC,
though the entries in LDAP of all my computers exist,
why does this happens.
After Rejoining, i often get the following messages in /var/log/messages  in
my PDC server
1.creds_server_check:- credential check failed
2. smbd api_samr_set_userinfo: Unable to marshall SAMR_Q_SET_USERINFO
3. net_sam_logon: creds_server_setup failed. Rejecting Auth Request from
cleint TEST1$ machine

I have file server having redhat linux 4 and samba 3.0.10 , which is joined
to PDC, The smb.conf i have given security=domain, and workgroup i hav
mentioned the domain name .
i have given the following command to join the fileserver to my PDC,
system#net rpc join -U root%not24get
Joined to MYDOMAIN.COM

the above message says, that it has joined to domian, but when i give
command
system#net rpc info
i get the following message
rpc_parse/parse_prs.c prs_mem_get(537)
prs_mem_get: reading data size 14418130 would overrun

please guide me , this is creating huge problems.
