Cannot reproduce here, but I have heavily working Firefox with insane amount of tabs, so maybe it is just hidden in other activity. *** Bug 445568 has been marked as a duplicate of this bug. *** I'm also seeing this problem with: xulrunner-1.9-0.60.beta5.fc9.x86_64 firefox-3.0-0.60.beta5.fc9.x86_64 Firefox starts thrashing the disk almost every time a few minutes into the session no matter what website. Vmstat tells me the CPU is 50%-90% waiting on IO fairly consistently for more than 5 minutes at a time. I have the same problem here. iotop's (yum install iotop) most actives (examples while Firefox is running): PID USER DISK READ DISK WRITE SWAPIN IO> COMMAND 477 root 0 B/s 22.64 K/s 0.00 % 99.99 % [kjournald] 3293 ferrogoo 116.37 K/s 72.73 K/s 0.00 % 99.99 % firefox -UILocale de ...

PID USER DISK READ DISK WRITE SWAPIN IO> COMMAND 3222 ferrogoo 290.78 K/s 207.18 K/s 0.00 % 79.13 % firefox -UILocale de 477 root 0 B/s 0 B/s 0.00 % 61.14 % [kjournald] 214 root 0 B/s 0 B/s 0.00 % 19.37 % [pdflush] It takes about three minutes to complete. Part of the time Firefox does not respond to any user interaction. Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Per http://jasondclinton.livejournal.com/66300.html , looks like this may have something to do with upstream bug https://bugzilla.mozilla.org/show_bug.cgi?id=421482 (and peripherally http://bugzilla.kernel.org/show_bug.cgi?id=9546 ) I see this, too. The IO bursts seem to be periodic, and strace'ing firefox during one of those peroids shows it happily working it's way through urlclassifier*.sqlite. Streaming reads from the same filesystem (movie playback) completely stalls during those reads. *** This bug has been marked as a duplicate of 439908 *** *** Bug 452718 has been marked as a duplicate of this bug. *** |
