Error description

  • It appears possible that after the smx connection is lost
    between the RSS and it's primary, when the RSS goes to
    reconnect, it can successfully reconnect at the smx level, but
    still leave the server in it's update blocked state.  In the
    MSGPATH file the following messages would be seen.
    
    First to show the disconnect you'd see the following:
    
    08:31:53  The SMX connection between high availability servers
    was closed because the
     peer server was unresponsive for the timeout period (60 seconds
    times the
     number of retries).
    08:31:53  The SMX connection between high availability servers
    was closed because the
     peer server was unresponsive for the timeout period (60 seconds
    times the
     number of retries).
    08:32:00  The SMX connection between high availability servers
    was closed because the
     peer server was unresponsive for the timeout period (60 seconds
    times the
     number of retries).
    08:32:01  RSS: Lost connection to pri
    08:32:01  Updates from secondary currently not allowed
    08:32:01  Updates from secondary currently not allowed
    08:32:01  Updates from secondary currently not allowed
    08:32:01  Updates from secondary currently not allowed
    
    The above shows the smx connection dropping, then the RSS
    reports the connection lost and then the updates blocked
    messages.
    
    Now if the updates get left in the blocked state, when the RSS
    connects you would only see something like this for the
    reconnect:
    
    08:32:12  RSS: Reconnected to pri
    
    However, if the updates were correctly unblocked you should also
    see messages like the following as well:
    
    08:29:28  Updates from secondary allowed
    08:29:28  Updates from secondary allowed
    08:29:28  Updates from secondary allowed
    08:29:28  Updates from secondary allowed
    
    Also, in the case where updates are blocked, in onstat -g ath
    there will be an absence of proxySync threads.
