I encountered the same problem at our school with a multiple server setup of ubuntu hardy and Firefox 3.01. No way to keep students working.
We should collect some more information to ensure not to mix different issues: 1.) Is this only a problem with Firefox 3.01 or shows Firefox 2 the same in hardy? 2.) What kind of lock files do you get in the various situations? (cd to firefox profile, ls -la | grep lock) case a. firefox starts normally b. firefox start is delayed c. firefox terminates with message "Firefox is already running" d. firefox crashes without message 3.) Are you working on multiple servers with home directories mounted via nfs? 4.) What happens if students start the browser from terminal with the command firefox -save-mode ? Explanation to Question # 2.): I have looked at the firefox profile and the profile locking mechanism where I suppose the cause of our problem. I found out that Firefox 3 has a different mechanism of profile locking. In the profile folder (/home/user/.mozilla/firefox/xyz.default/) a symbolic link is created by the starting firefox: ls -l shows the link named "lock": lrwxrwxrwx 1 wollw wollw 15 2008-09-08 20:32 lock -> 127.0.1.1:+6164 The link disappears as firefox exits. I am not familiar with the strange "->Ip:+Number" syntax, which are the loopback IP and the process number of the firefox process. Can someone explain what kind of link this is? Appending text to the file and reading from it shows that it is a kind of named pipe. If I remember correctly: Former versions of Firefox had just an ordinary file named "lock". In consequence to this change a second firefox process now just opens a new window but gets part of the existing process while in former versions the second process terminated with the error message "Firefox already running". Please have a look at the lock file. In another situation even on the local machine insted of loopback IP the IP of the interface eth0 is given: lrwxrwxrwx 1 wollw wollw 19 2008-09-08 21:58 lock -> 192.168.0.20:+21469 I describe this in fully detail as we have a multiple server environment with three secondary servers and one primary ltsp server which holds the home directories (and therefore the users firefox profiles. The home-directory is mounted by nfs. There are issues at bugzilla about former versions of firefox with profiles at nfs mounted locations. -- Extreme slowness, "Firefox is already running" error for >3 users launching Firefox in LTSP environment https://bugs.launchpad.net/bugs/269188 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
