Do not ascribe to the whole community the shortcomings of an individuals

Unless you have 15000 servers connected the fact you have that many 
processes indicates a serious issue with the server or at least one of 
the clients. Samba creates just 1 single process per client and all its 
requests are served by that process. If you are seeing multiple 
processes it means the client is opening multiple connections. That is 
wrong and indicate there is probably a bug with either server processes 
crashing, becoming unresponsive or both, or the client misbehaving..

You may want to consider trying playing with the following parameters on 
your samba server:
- deadtime
- max connections
- keepalive
- reset on zero vc

You may also want to prevent samba from dumping core if that is 
activated as it could put pressure on disks and the kernel if too many 
processes core all at once.
