We often come across issues with cam communication such as agent registration issues,camping timeout messages or issues related to DSM Explorer being slow and CA Support advises clients to make a configuration change to the cam.cfg to set disable_proxies = yes. We recommend that the change be made on all Domain Managers and on the scalability servers or where the message occurs.
This is documented in the following technical document TEC539203.
Other tips related to setting this value
1. make sure that in the disable_proxies = yes line that you have a space after "s" and "=" and between the "=" and the letter "y".
2. after saving the cam.cfg run on a command line:
camclose &cam stop -c -l
To verify if you have this issue occuring open the %CAI_MSQ%\logs\DG0000#.logs and look for messages as
queue 126.96.36.199:4104 reversed identity with proxy 188.8.131.52:4104
Hope this is helpful
