Description of problem: F16 Firefox seems to crash quite often when I am browsing. A crash dialog appears and the report is sent to mozilla.org. I thought I better file a fedora bug to track this issue. Version-Release number of selected component (if applicable): firefox-6.0-1.fc16.x86_64 How to reproduce: 1. Install F16 Alpha Live x86_64 2. Browse around blogs from start page. Actual results: Firefox crashes quite often spontaneously while browsing. I have a feeling that when it crashes it is usually after rendering a page. Expected results: No crashes. Additional info: I haven't seen crashes under i686 yet.
I will try an upstream build later to confirm it is not some toolchain issue.
Hmm after latest yum update today I haven't seen any crashes today. Maybe newer kernel? (I am now running kernel-3.1.0-0.rc4.git0.0.fc16.x86_64.)
This is almost certainly a dupe of #730856, which causes exactly this symptom (sporadic crashing in any app that does lots of DNS lookups, usually observed in Firefox).
Thanks, Adam - I think you're quite right. I am back in the office today and had a crash in about 5min. Strange that it is ok at home but not in the office - must be some dns difference. Closing as a duplicate of glibc bug 730856, though dunno if it is better to keep this open until glibc gets fixed for other people to know. *** This bug has been marked as a duplicate of bug 730856 ***
jens: the bug tends to resist 'patterns' because it happens when you get one of three fairly unusual responses from the DNS server; no DNS server is very likely to give out these responses _consistently_ over a long period, but most servers will give one of them out every so often, sometimes for - say - 15 minutes for a particular domain...so you think you have a reproducer, you go have lunch, and suddenly it's not a reproducer any more...
