Greetings. I am having issues with rpm/yum on a centos 5.2 x86_64. I am trying to update from 5.2 to 5.4. During yum update, the application became unresponsive during the package search. It had not begun to download any packages. I tried to do a "yum clean all", but that wouldn't complete either. I tried to do a rpm --rebuild, but that failed with a segmentation fault. Tried it a couple of times... Reboot didn't work. I copied the database files out of /var/lib/rpm to a safe location, then deleted the __db.* files. Ran rpm --initdb. That seemed to work. Now, I've been running rpm --rebuild for around 18 hours. The load factor on the server is 1.0, according to uptime. Top shows that it is running, using 100% cpu. Iostat shows around 25% usr load. I see the os raid drives bounce on occasion. ps -ef shows the following daemons running (applicable to rpm): /usr/lib/rpm/rpmd --rebuilddb /usr/lib/rpm/rpmq -q --all --qf %{name}-%{version}-%{release}.%{arch}.rpm\n /bin/sort A search of google led to no real help, but I may be searching wrong... Here are the specs: Centos 5.2 kernel: 2.6.18-92.1.6.el5 #1 SMP x86_64 2 xeon 3.20ghz procs, 4 logical I can't get the rpm or yum version, since rpm is still running. This is a stock install, using the xfs kmod. Only non-standard app installed is the 3ware utilities. I have run a yum update on another 64bit box (almost identical hardware) and a 32 bit box with no problems. The boxes were at 5.2 and 5.0, respectively. Any thoughts? Thanks, Monty
