[rbak-nsp] Maximum SSH Administrator sessions

We are experiencing maximum SSH session limits other than the configured value.

Log:

System Bootstrap version is Mips,rev2.0.2.69
Installed minikernel version is 11.7

Digging through documentation states that there is a system limit for active remote administrators of 20 per context (telnet + ssh) and a system wide maximum of 100.

We seem to get this error when the 16th session attempts to extablish.

I feel like I am missing something but I do not know what. Is there a hard limit for the local context that is not documented? Is this a bug in my SEOS release? Any help would be appreciated.
