Comment 1 Eliran Itzhak 2007-09-29 09:23:05 UTC
Forgot to say in my original bugzilla post.
I statred getting this error yesterday, after the latest yum update.
Until then, Never had such a problem with yum.
I've made no special changes to the system, just yum updated.
Thanks.

Comment 2 Eliran Itzhak 2007-09-29 09:41:58 UTC
I've just found out that the problem is with a yum plugin called "fastestmirror".
If I do "yum search kernel --disableplugin=fastestmirror" everything works well.
The problem started yesterday, and I've made no changes to the system except yum
update.

I have the following yum plugins installed. "downloadonly" & "fastestmirror"

I've removed "yum-fastestmirror" (the problem went away) and reinstalled it (the
problem came back)

Comment 3 Tim Lauridsen 2007-09-29 13:17:36 UTC
Yes, as you already have detected does the problem occours in the fastestmirror
plugin.

Luke, Any comments

Comment 4 Luke Macken 2007-12-07 11:57:28 UTC
I patched fastestmirror the other day to make it throttle the way it dispatches
threads.  It adds a 'maxthreads' configuration option, which defaults to 15. 

Please put this file in /usr/lib/yum-plugins and try and reproduce the issue.

Comment 5 Luke Macken 2008-01-25 19:52:18 UTC
yum-fastestmirror-1.1.10 has been out for a while now, which should resolve this
issue.  Please re-open this bug if this problem still occurs.  Thanks!
