Hello Lee,
That change will disable DA. DA alerting is heavy used in ATC, i would not recommend this.
You should investigate why the agent are continuously disconnecting and connecting
I suggest you to start fixing any possible configuration issue in your setup and implement all common best practices, I have summarize most of them here:
Introscope Enterprise Manager Troubleshooting and - CA Knowledge
And very important, if possible try to upgrade to the most stable release, to obtain a copy of the latest hoftixes for 10.5.xor 10.7.x code branch you would need to contact Support
If the problem persists, open a support case and include a copy of all logs and config directories from the EMS.
As this is an issue with LB mechanism, we would need DEBUG logs from MOM(s) for a few minutes only (10 -15), this will help us understand the root cause of the disconnection
I hope this helps,
Thank you,
Sergio
