The child process that you are referring to is a forked smbd process, I

The normal way smbd works is to have one parent process, which forks a
child smbd to handle each incoming connection. The child persists as
long as the client machine stays connected, and handles all the requests
from that client. When the user of the client disconnects all shares,
logs off or shuts down the machine then the connection to the server is
closed and the child smbd exits.

So: if you have several hundred clients logged in to a server
simultaneously then it is normal for you to have several hundred smbds
running (much as you would have several hundred telnetd, rlogind or
sshds running if all those people were shell users).

If however you're saying that smbds are being created per individual
file operation and then aren't aren't going away, or if smbds aren't
going away when clients disconnect from the server, then something odd
is going on.
