Re: All nginx lookup handlers are unavailable while SSL handshaking to lookup handler
I am having this exact problem on a single server system.

Re: All nginx lookup handlers are unavailable while SSL handshaking to lookup handler
i think that the problem for me is that the mailboxd (which is http+pop+imap) is getting totally overwhelmed
I have zimbraHttpNumThreads set to 20, i think this may be too low
I also dont know what impact that setting has on the nginx auth stuff

Setting
su - zimbra -c 'zmprov ms (server) zimbraHttpNumThreads 60'
then
sudo -u zimbra /opt/zimbra/bin/zmmailboxdctl restart
has reduced it a log for me, though cpu usage is now through the roof
