I'm curious - how long does it hang? Does it hang forever? Could try connecting to a different mirror? I've heard of someone else having similar problems connecting to download.fedora.us before and I'd like to remove some variables. FWIW, I frequently get hangs while reading from socket from download.fedora.redhat.com. Patient persistence, or trying another mirror worksforme. Created attachment 97933 [details]
yum configuration file
Seth Vidal asks how long it hangs. The answer is that I've left it hanging for an hour or so before giving up. Would it help if I left it overnight, to get another data point? It seems pretty clear that I'll get the same results, since (a) the hour I've waited is significantly longer than the 1/4-hour time required to rebuild the RPM database [suggesting to me that there is no yum-related computation of that scale] (b) there are no noticable disk accesses [suggesting to me that the calculation is not doing anything productive] (c) there are no noticable file transfers over my broadband connection [suggesting that the yum work is not limited by a large amount requisite data] In summary, the yum process takes nearly 100% of the CPU without, as I said, printing anything even at the highest 'verbosity' level, noticibly accessing the disk, or accessing the internet. And it uses that CPU resource over a timescale longer than I would expect, based on inferences from similar work. I hope this helps. As I said, I could leave it running overnight, so that I could post here again and report a larger number. But it would seem to be more sensible for me to do other tests, and I'd be happy to do so, if advised. In case it helps, I've attached my /etc/yum.conf file. Maybe I'm just being wrong-headed about it. (I am a yum newbie, but I'm hopeful!) 1. why did you disable keepalive? 2. setting retries to 0 makes it try forever for a failure. I'm betting your retries statement is the source of the problem. -sv I've experienced such hangs also, and am doing right now. Its been going for several hours, but there is no cpu usage, contrary to what Dan is finding. I have experienced such results with all yum versions I have had. Previously it has been due to rpm hanging, but with fc2 dev versions there has been no rpm instance running. The configuration is default appart from some mirrors of fedora.us and my own mirror of the redhat server. kill -9 <process_id> has no effect on the process. Current is latest as of this post. Place of freeze is just after all the list of repositories has been printed. The 1st problem appears to be resolved, use mis-configuration. #2 smells like a stale rpmdb lock because of no cpu usage. Try rm -f /var/lib/rpm/__db* to remove stale locks. Please reopen if stale locks was not the problem. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040207 Firefox/0.6 StumbleUpon/1.66 Description of problem: Yum hangs, no matter what I try to do with it. In particular, 'yum -d3 install yum' produces some output and then it stops producing output. A tail of the output is given in the next section of this report. I have a broadband connection. Yum has been sitting there, producing no output but using most of my CPU power, for over an hour. It is not causing any disk accesses, nor is my cisco675 conector indicating access to the outside world, so I assume it is hung. Version-Release number of selected component (if applicable): yum-2.0.4.20040103-2 How reproducible: Always Steps to Reproduce: 1. run 'yum info' or 'yum list' or 'yum install yum' [probably others] 2. 3. Actual Results: Best ver+arch installed for kernel is i686 Downloading needed headers getting /var/cache/yum/updates-released/headers/pango-0-1.3.2-3.i386.hdr Disabling Keepalive support by user configuration failover: baseURL = http://download.fedora.us/fedora/fedora/1.90/i386/yum/updates failover: path = /headers/pango-0-1.3.2-3.i386.hdr Expected Results: Installation. Additional info: I removed all the mirrors because I had worse results. (Trust me, I spent hours trying to find workable mirrors.) I'd like to use yum because it is reputed to be faster than up2date. The latter is terribly slow, e.g. 1/2 hour to install a package, on my P2/300MHz/128RAM/broadband system. Thanks.
