Thanks for your replies, very much appreciated.
I know for sure the mass inserts are not happening, but the restart of the service sounds like a possible cause.
Normally i would not have a problem with it, but the thing is that the cilent sees these gaps as well, so i need to reassure him there is no problem.
So you are sure there is no reason for alarm?
If they happen more than often i should probably find the cause of the restarts of the service?
