Public bug reported: Binary package hint: firefox
http://www.emapsite.com/ has a system called plans ahead which I am partly responsible for. It uses a java applet to display mapping, and interacts with javascript on the surrounding page. You have to log in to see the page, but it's a free registration. Currently on my machine firefox hangs when launching plans ahead, leaving one of my cpus at 100%. I get a grey box where the applet would be, and firefox stops rendering completely (dragging another window over firefox leaves a trail that never gets cleared up). I was on jre 1.6.0_10, I tried updating to jre 1.6.0_12-b04 (the latest from sun), but didn't help. It always used to worked with no issues on my ubuntu / firebox, and we haven't altered the applet for some time. I'm guessing what has changed is an update to firefox, though I'm not sure how long this has been happening. I can attach the netbeans debugger to the java process (once I'd figured out how to do it), and the java threads all seem to be running without error. I think, but I'm not sure that the applet's init() method is stuck on a line that reads: win = JSObject.getWindow(this); which as I understand it is obtaining a reference for communication with firefox's javascript engine (liveconnect?). Attaching strace with -p to the firefox process rapid and repeated output of exactly the following: strace -p 18213 read(97, 0xbff2ae8c, 4) = -1 EAGAIN (Resource temporarily unavailable) read(97, 0xbff2ae8c, 4) = -1 EAGAIN (Resource temporarily unavailable) etc... I'm not really sure what to make of this at the moment. I'm guessing it's an obscure bug in ubuntu's build of firefox. version info: ff v3.0.6 - Installed: 3.0.6+nobinonly-0ubuntu0.8.10.1 Linux emap-eve-pctim 2.6.27-11-generic #1 SMP Thu Jan 29 19:24:39 UTC 2009 i686 GNU/Linux Ubuntu 8.10 java jdk/jre 1.6.0_12-b04 LSB Version: core-2.0-ia32:core-2.0-noarch:core-3.0-ia32:core-3.0-noarch:core-3.1-ia32:core-3.1-noarch:core-3.2-ia32:core-3.2-noarch:cxx-3.0-ia32:cxx-3.0-noarch:cxx-3.1-ia32:cxx-3.1-noarch:cxx-3.2-ia32:cxx-3.2-noarch:desktop-3.1-ia32:desktop-3.1-noarch:desktop-3.2-ia32:desktop-3.2-noarch:graphics-2.0-ia32:graphics-2.0-noarch:graphics-3.0-ia32:graphics-3.0-noarch:graphics-3.1-ia32:graphics-3.1-noarch:graphics-3.2-ia32:graphics-3.2-noarch:languages-3.2-ia32:languages-3.2-noarch:multimedia-3.2-ia32:multimedia-3.2-noarch:printing-3.2-ia32:printing-3.2-noarch:qt4-3.1-ia32:qt4-3.1-noarch ** Affects: firefox (Ubuntu) Importance: Undecided Status: New -- firefox hangs for emapsite applet, strace shows EAGAIN repeatedly https://bugs.launchpad.net/bugs/331962 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
