Hi Abu,

Correct me if i am not correct. I hope you are investigating against broker which has multiple concentrators as data sources. While investigating, one concentrator may be offline.

When the concentrator service is offline, Please check below in Concentrator putty.

- status nwconcentrator 

- Check /var/log/messages if it is reindexing with similar logs in https://community.rsa.com/docs/DOC-46141

Hi Sravan,

yes, we have multiple concentrators under broker.

and this issue is occurring when we troubleshooting the meta values in index custom.xml file

Hi Abu,

Thanks for more details. So, After editing index-concentrator-custom.xml, you may need to restart concentrator service. During that time, Concentrator service may go offline till service initialized.

HI Abu,
