SiS in HA event close key misbehaviour

Hi experts. We have SiS 11.24 in HA. We also have BSM integration for events. We have lets say a simple db query which is green. When primary sis goes down failover takes over. And lets say that at that point the db query monitor turns in eŕror. We get the event in OMi. Now primary sis takes over again and runs the monitor and the monitor in now ok again. The thing is that the event from sis2 will not close in bsm since key contains the sis server name and does not autoclose when normal. Is there any suggestions? I read something about dyn files and merge back. Another idea we had is the mapping file but we do not want to wxclude the sis server name from the close key
Thank you
