Hello, I tried all of the above, and nothing works.

especially, I tried:
rm -f /var/lib/rpm/__db*

I also tried rpm --noscripts

strace of my rpm command is:

stat("/usr/lib/rpmdb/x86_64-redhat-linux/redhat/__db.001", {st_mode=S_IFREG|0644, st_size=16384, ...}) = 0
open("/usr/lib/rpmdb/x86_64-redhat-linux/redhat/__db.001", O_RDWR) = 8
fcntl(8, F_SETFD, FD_CLOEXEC) = 0
fstat(8, {st_mode=S_IFREG|0644, st_size=16384, ...}) = 0
close(8) = 0
open("/usr/lib/rpmdb/x86_64-redhat-linux/redhat/__db.001", O_RDWR) = 8
fcntl(8, F_SETFD, FD_CLOEXEC) = 0
mmap(NULL, 16384, PROT_READ|PROT_WRITE, MAP_SHARED, 8, 0) = 0x2a98782000
close(8) = 0
futex(0x2a98782000, FUTEX_WAIT, 2, NULL) = -1

Can someone give me more background information regarding this.

I have only had this problem on one particular system:
Dualcore E6420
Redhat 4.4 or centos 5.0 or centos 5.1, always same hang during the rpm install.
The only way I got it to work was by installing vmware and installing Redhat 4.4 under that virtual machine. But I need very high performance (VOD server application), so I need to run linux natively.

Do you think there is something I should disable in the bios of that machine?

Thanks for any hint you can share!

I just disabled the L3 cache of the processor from the Bios, and now I can install my RPM.

Can someone please comment why that seems to solve the problem???

When I said:
I meant what is on thread http://www.linuxquestions.org/questi...4/#post2990978

What really solved the problem of rpm hang for me was erasing files in /usr/lib/rpmdb/x86_64-redhat-linux/redhat/__db.00*
then running rpm --rebuilddb

So it seems I am one of the very few running Linux in 64 bit mode ...

strace command helped me find the solution
