Increase the retry delay

Hi Team,

I am trying to flush the dispatcher content from AEM author using ACS commons dispatcher flush console.

I am able to flush the sepcific page from the ACS commons dispatcher flush console but If I try to flush the root level like /content, it is not flushing and hanging ACS commons dispatcher flush console page.

Can you please suggest on the above.

also can I increase the Retry Delay value from 60000 to 600000?

Thanks & Regards

Veera
