I modified the entries you listed below and started running a few instances of SVN on the shares and it seems to be holding steady.
I'm going to continue testing during the day to see how it does.
Looking back on the issue I never noticed the date in which the files were accessed. The Samba clients would be done with a file but the server never clicked in that it should release the files.
Like I said I'm going to continue the testing on this to make sure it stays consistent with the current results.
Thank you very much for the suggestion.

Do not ascribe to the whole community the shortcomings of an individuals the volunteers 'his' opinion please.

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:
- max connections
- 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.
