Hi, we are running Zimbra 5.0.15 as a mailservice here and have problems with the stbillity of the http(s)/imap(s)/pop(s) proxies. We see the nginx workers on the boxes using after a while 100% CPU and if all workers are on 100% on one of the CPU's the Nginx does not respond at all to requests. The OS we are running is Red Hat Enterprrise Linux 64, Nginx Version 0.5.37, memcached 1.2.5.by elvis00 - Nginx Mailing List - English
