Red Hat Bugzilla – Bug 455010
setroubleshoot browser hangs when marking a large number of events
Last modified: 2009-06-10 06:46:50 EDT
Description of problem:
I selected all (Ctrl-A) and did edit->Mark Delete and the process hung. Strace
of sealert shows it hung here:
sendto(13, "content-length: 778\r\ntype: metho"..., 829, 0, NULL, 0
strace of setroubleshootd shows it hung here:
sendto(10, "content-length: 135\r\ntype: metho"..., 193, 0, NULL, 0
The wchan for each of these processes is sock_alloc_send_skb. It looks like
you're overflowing the send buffer. Here are the kernel stack traces:

This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '9'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 9's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 9 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
I believe this is fixed in the current release.
