You have two problems here.  The first is that you are having multiple
people logging on as the same user id.  This is not a good idea.  There
are internal tables that will get filled up this way, and possible
prevent anybody from logging on in the future.

Your second problem can be solved by increasing the following parameters
by using the /usr/sys/conf/configure program:

Parameter	Description				System default
NINODE		maximum open inodes per file system	   100
NFILE		maximum open files per file system	   100

Try increasing them to 150, then to 200 if you need it.  BTW, where did
you get that figure of 300 for the maximum open files systemwide?
