You reported Hung PRIME Administrator logins in ALPSGANZ11G.  Need to know why.

Prime is currently configured to hold 2 connections per ASR to support the scripts that Prime runs on these boxes. Since there are 2 Prime instances that manage the ASRs concurrently, there should be at minimum 4 CLI connections from Prime (2 connections from Prime site 1 and 2 connections from Prime site 2).
However, some node has 5 sessions, some has 2 sessions, and some has 4 sessions.
In below example, m70370, is a prime user with 5 sessions.
