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?
