If you did not set that option, you do have a problem.

See, once again that needless info log comes in handy. ;) See the
prefork: child states: II
lines. They are generated at the point where the prefork algorithm
decides if more or maybe less worker children should be around, so about
after a message has been processed.
You can easily see there are currently two children, both idle (I), none
busy (B) processing a message. If your system is really busy processing
lots of messages, you'd see the number raise up to max-children -- and
eventually go back down with load decreasing.
Unless you do see constant higher load and busy children, low settings
are just fine. Even if occasionally all your fetchmail instances would
hammer away at SA at the same time, there is no need to raise the number
of children. Mail will simply be queued and processed once a spamd child
becomes idle. A delay of a few seconds, hardly worth the additional
resources needed to keep around lots of spamd instances at all time.
