  loses power while booting up

- SNMP CERT Security Advisory

- Traps were only sent to the first configured trap host

- Resolved server lockup when using lpr/lpd and the printer goes offline. When offline, 
  lpr continues to send print requests that get queued up in the IOLAN.  The lpr client  
  closes the TCP connection after a while.  When the printer goes online again ( after 10 
  min), IOLAN tries to process the print request but get an error.

  for IOLAN server
