Nope, this does not indicate a crash. In fact, it is perfectly normal.

Prefork is an efficient default algorithm for spawning children, before they are needed, thus having spare ones available. The II means, that at this point (right after the last scan has been done), both children are idle (state I).

The S you quoted above means, one children still is being spawned. B indicates a busy child.

The states are being reported per child. With the default of 2 children at startup, seeing only one letter here would indicate a crashed child. More than 2 can be reached, if your SA is really busy.

FYI, these log message (usually right next to each other in your mail log) would indicate a crashed child:

  spamd: handled cleanup of child pid 11309 due to SIGCHLD   prefork: child states: I
