How to configure rsyslog queues to multiple remote servers

Issue

• Slowing down machine if syslog server not available
• We had an issue where the syslog was slowing down a machine because one of the syslog servers was not available.
• Currently we forward everything to 2 syslog servers with the following rules

     *.*             @@loghost1.example.org
     *.*             @@loghost2.example.org

• What would be the best solution to prevent the system from slowing down? I was thinking of using queues.

   $WorkDirectory /var/spool/rsyslog 
   $ActionQueueType LinkedList     
   $ActionQueueFileName rsyslog 
   $ActionResumeRetryCount -1 
   $ActionQueueSaveOnShutdown on 
   $ActionResumeInterval 10
   $ActionQueueSize 50000 
   $ActionQueueDiscardMark 40000 
   $ActionQueueHighWaterMark 40000  
   $ActionQueueCheckpointInterval 100
   $ActionQueueMaxDiskSpace 2g
   $ActionQueueTimeoutEnqueue 10
   $ActionQueueDiscardSeverity 0

• Is there better ways to solve this issue?
• We don't like to use disk queues but just memory.
• I guess I still need to define the QueueFileName as I have to use 2 different queues.
• How can I prevent from dumping to disk?
