 3. Alerts 
 =========

 3.1 All alerts except OOLs and missing scientific data

   * Level 3:
 
 305 IBIS synchronization failed too many times, 3000 times!
     Long description of ISDC alert 14408733:
     Program / version that has created this alert:  Preproc 5.8
     Directory of alert generation:  /isdc2/run/alert/nrt_pp
     Preproc seems unable to resynchronize the IBIS time!!! Preproc must be restarted?
