CAM is the highway (or underlying protocol) that all ITCM communication uses.
If that highway is liter with traffic, it will slowdown all traffic going over that route.
This slowdown can cause issues with Asset management and Software Delivery, so it is a good thing to check on.
In the newer versions (R12.8 and R12.9) we have seen on many Enterprises, Domain Manager's,
and Scalabilities issues with a legacy piece of CAM.
To see if you have that issue, you need to look at the CAM logs in the %cai_msq% folder,
OR the CA\SC\CAM\logs folder or CA\SC\CCS|CAM\logs folder
Look at the dgXXX file and look for the following lines:
queue ***.***.***.***:4104 reversed identity with proxy ***.***.***.***
To remove these errors either follow the following steps OR open a support case.
Recheck the logs after a few hours and see if all the reversed identity with proxy messages are gone.
If you have questions or if you run into any issues after doing the above, please enter a Support issue.
