Hi, I am having strange problem lately. I figured out that when I go to certain site, firefox takes forever to loead up to the point that it seems like computer is being freezed (everything stops responding). But after sometime, firefox terminates abruptly without any warning. when I tried to look at the /var/log/messages I found out like this (lots of same message repeating): ================ Jan 12 10:58:47 zeesrvr kernel: [<c04038a1>] error_code+0x39/0x40 Jan 12 10:58:47 zeesrvr kernel: DWARF2 unwinder stuck at error_code+0x39/0x40 ================ At the status bar of the firefox, I noticed the message "Waiting for statrafogon.biz..." when this happened. I tried to check the with same website from windows-firefox and norton antivirus tells me that it has detected and removed a virus called "downloader.exe" from firefox cache and the message repeats forever. I was using firefox 1.5.0.8 and now updated to 1.5.0.9 and problem remains same. This condition doesn't happen always. I guess when the website hosting the banner ad try to load certain ad from other website (but not sure). I noticed that usually these ads are placed recently on the BitTorrent tracker sites like "mininova.org", demonoid.com etc. Before I thought I have problem with my hardware but hardware seems fine. Now other questiong remains? 1) Is there a bug in firefox? or flash plugin? 2) Is the ad company trying to inject malware? 3) any bug on FC5 kernel itself? Can somebody confirm if this is true for you too? Thanks in advance
