Yum version 2.2.0-1 hangs when running yum install

Hello
 
I have a problem with yum install command. The environment is the
following:
 
- Diskless server (the whole server's OS (RHEL 4) is located on NFS).
See below mount command output from server:
 
#mount
rootfs on / type rootfs (rw)
10.10.17.45:/opt/nfsroot/10.10.17.46/root on / type nfs
(rw,v3,rsize=32768,wsize=32768,hard,tcp,nolock,proto=tcp,timeo=600,retra
ns=5,addr=10.10.17.45)
/proc on /proc type proc (rw,nodiratime)
/proc/bus/usb on /proc/bus/usb type usbfs (rw)
/sys on /sys type sysfs (rw)
none on /dev type tmpfs (rw)
none on /dev/pts type devpts (rw)
none on /dev/shm type tmpfs (rw)
none on /tmp type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)

With rpm command I can install rpms remove rpms etc. without any
problems. The problem arise for example when I'm running command "yum
install [pkg]". This yum install command generates "Segmentation fault"
error or it just hangs (See below listing).

Segmentation fault

After this unsuccessul yum install command all yum commands hangs and
also all rpm commmand hangs. To solve this problem I have to run the
following commands:
 
# rm -f /var/lib/rpm/db* 
# rpm -vv --rebuilddb 
# yum clean all
 
After this I can run all rpm command and also yum list command but when
ever I try to run yum install or yum update I get the "Segmetation
fault" error and I have rebuild rpm databases.
 
When I moved /var/lib/rpm directory's files under /tmp directory and
configuring yum and rpm use /tmp directory for database directory yum
install command works without any error. Is this issue related some how
with NFS or related with rpm/python versions or what...?
 
So  could you help me fix this problem and currently we are using the
following versions of rpm, python and yum
 
- rpm-4.3.3-22_nonptl
- rpm-python-4.3.3-22_nonptl
- rpmdb-redhat-4-0.20070421
- rpm-libs-4.3.3-22_nonptl
- libxml2-python-2.6.16-10
- python-2.3.4-14.4
- yum-2.2.0-1
 
And we like to continue to use yum version 2.2.0-1. We also installed
yum version 2.4.3-4 with the dependencies but we got the same error.
 
regards, Timo
