[Samba] winbindd terminates with INTERNAL_ERROR

[Helmut Stock]

my environment samba  3.0.14a , w2k ADS/kerberos, winbind +  idmap_rid 
on IBM x345

we installed samba 3.0.14a on several servers using RedHat AS2.1 and 
AS3.x by rebuilding the binaries from samba-3.0.14a-1.src.rpm.

everything works perfect and smooth
-> CONGRATULATIONS TO THE SAMBA TEAM !!
creating a kerberos  ticket, joining the domain and browsing network 
shares is performing as expected on 4 servers except only ONE machine.

on this one, i had installed an orignal redhad samba  2.2.7 package 
before upgrading to  3.0.14a. all old packages from the previous release
were removed (samba-client-2.2.7-1.21as, samba-common-2.2.7-1.21as, 
samba-2.2.7-1.21as, samba-swat-2.2.7-1.21as) as well all directories 
relating to samba (/etc/samba and /var/cache/samba).
i joined my w2k domain and can connect to shares but continously receive 
the error "process_loop: Invalid request size".
after several hours my winbindd terminates with:

[2005/04/24 09:12:01, 0] lib/fault.c:fault_report(37)
  INTERNAL ERROR: Signal 6 in pid 4071 (3.0.14a)

i have checked all servers for /lib/libnss_winbind.so and 
/lib/security/pam_winbind.so files. they are all the same size and date 
since they came from exactly  the same rpm.

can somebody point me to a direction how to fix this. i cannot explain 
why winbindd works perfectly on three servers but panics on another.

thanks in advance
