Error description

  • albd_server should properly cleanup all associated sockets when
    encountering errors on the creation of a forked process
    
    
    
    ClearCase 7.1.2.x
    
    
    Solaris 10 x86
    
    
    
    The issue has been reported where setting the MSADM_SVR_PORT
    within the
    /opt/rational/clearcase/config/services/albd_rt_params.conf can
    cause the msadm_server not to spawn when requested by a
    MultiSite client.  The following error is seen within the
    albd_log at the time of the error:
    
    ?time? albd_server(*****): Error: Unable to allocate port in
    specified range: ?port?, ?port?
    ?time? albd_server(*****): Error: bind: Resource temporarily
    unavailable
    
    
    In performing an investigation, the IPv6 ?port? was already
    allocated to the albd_server and was causing the error to occur
    when the sockets for the newly requested process was being
    configured.
    
    Workaround:  Restart ClearCase on the affected server
