Wireless Access

what the action must taken to solve this issue in airwave?

It needs to be checked from the CLI on why it is stopped. Sometimes we would have to kill the process and restart based on log.
I would suggest opening a TAC case.

 * The PAPI handler server was kept restarting due to hostname unspecified in /etc/hosts file.  information.

* Added the hostname of the server in /etc/hosts file and restarted all the services.

* Switched to AMON preferred and the PAPI server is stable now.

this is the soultion , i know papi is message between controlle and airwave to make RF -plans so how it related to hostname of airwave ??

why we must configure airwave hostname in /etc/hosts ???

When we configure the host name on GUI Ampsetup --> Network page, it will get added automatically to /etc/hosts.
