The problem is probably related to your TCP/IP configuration. Attempt to
'ping' your ADSM server as soon as the error occurs.
In addition, use 'query opt' to check the following settings on your
ADSM server:

1. COMMTIMEOUT is on 60 (sec.) by default; increase to 900.

2. IDLETIMEOUT is on 15 (min.) by default.

Parameter COMMTIMEOUT is reset by the following ADSM command:

    adsm> setopt COMMTIMEOUT <new value>
