Error description

  • When starting the ClearCase "xclearcase" or "xlsvtree" graphical
    interfaces on Linux hosts, using an invalid path, or failing to
    provide a path, may cause the application to hang.
    
    strace shows that the application is stalled waiting for a
    FUTEX:
    close(4)                                = 0
    close(3)                                = 0
    futex(0x6755bd8, FUTEX_WAIT, 3812, NULL
    
    Collecting the process stack shows the following:
    #0  0x008bb430 in __kernel_vsyscall ()
    #1  0x0071310d in pthread_join () from /lib/libpthread.so.0
    #2  0x008f2f00 in ccthread_join ()
       from /opt/rational/clearcase/shlib/libatriaks.so
    #3  0x0091c40a in pfm_exit () from
    /opt/rational/clearcase/shlib/libatriaks.so
    #4  0x080544ec in vtree_start ()
    #5  0x080548f8 in xclearcase_main ()
    #6  0x0805f19d in main ()
    
    This occurs when the internal pfm_exit() routine or exit() is
    called with a -1.
