Hi all,

I try two way but can't work:
1. Renew certificate : How to re-create self-signed certificate in a multiserver platform? - Zimbra :: Wiki
2. Set zimbraHttpThreadPoolMaxIdleTimeMillis: zmprov -m -l mcf zimbraHttpThreadPoolMaxIdleTimeMillis 10000

Does anyone have any idea on how to solve this?
