>Description:
I use this as my ftp server for a client who has clients of their own, so as I create a client username and ftp folder, I also add myself to their group, using a seperate group for each client.  I am current a member of 13 groups, when I tried to add myself to the 14th, then I get remote disconnected, no error to speak of, just can't telnet or connect using samba.

 It sounds like you may be bumping into the limit on group membership: in 
 FreeBSD a user can only be a
 member of 16 groups due to a hard-coded limit in the NFS v2/3 protocol.  
 There are also slightly higher limits imposed by
 both the kernel and userland because of the expectation that a user will 
 only be a member of a small number
 of groups.   While it is possible to fix this limitation, doing so will 
 require quite a bit of work to change the data
 structures in the kernel and remove any limitations in userland programs 
 which process groups.
 
 To verify that this is the issue you've found, does the login problem 
 only occur when you're a
 member of 16 groups and everything works properly when you're a member 
 of 15 or fewer groups?
