Multi Server post install issues - super slow

Postby Stephen J » Wed Feb 14, 2018 10:07 pm

Hello,

I'm experimenting with a Multi Server configuration as I'm feeling like our Single Server is getting too big. I followed the installation guide for 8.8.5 on Ubuntu 16.04 and am installing 8.8.6. I have the following Servers
ldap
mta1
mta2
proxy
mbox1
mbox2

I'm running into a few issues.

1. I created an account on one of the mailbox servers and when I try to reach it on https://proxy.mydomain.com, it basically never finishes logging in. If I switch to html, it will load after awhile but each action is very slow. Here are some of the mailbox.log from the mailbox server where this mailbox resides.

root@mbox1:/opt/zimbra/log# tail -f mailbox.log

2018-02-14 13:14:55,996 INFO [MailboxPurge] [name=test@ldap.mydomain.com;mid=6;] purge - Purging messages.

2. Once I get the html client open, I then log out and it goes back to the login page and there is an error above the Username field that says ???remote.NOROUTE???

3. I'm seeing smtp delivery attempts from an mta1 to a mbox1 on port 25. My understanding was that this would be done by lmtp on port 7025. It is receiving connection refused which I verified with telnet is the response the mailbox server is giving.

I would greatly appreciate some input on what might be going on.

Hello,

1 - check the nginx log , it is known that there are some problem with nginx in ZCS 8.8.x
2 - see point 1
3 -delivery on port 25, check the account is trying to deliver and the zimbraMailTransport associated with it.

Regards,

Thanks for the quick reply DualBoot. That got me some progress because I found a I had an incorrect DNS entry for the mailbox server so it was asking a non-existent server.
I'm still getting really slow. Here is what I'm getting in the nginx log

2018/02/14 14:53:47 [error] 1521#0: *5 upstream timed out (110: Connection timed out) while connecting to upstream, client: 192.168.0.220, server: proxy.mydomain.com, request: "GET / HTTP/1.1", upstream: "https://192.168.10.46:8443/", host: "proxy.mydomain.com"
2018/02/14 14:54:16 [error] 1521#0: *5 upstream timed out (110: Connection timed out) while connecting to upstream, client: 192.168.0.220, server: proxy.mydomain.com, request: "POST /service/soap/EndSessionRequest HTTP/1.1", upstream: "https://192.168.10.46:8443/service/soap/EndSessionRequest", host: "proxy.mydomain.com", referrer: "https://proxy.mydomain.com/"
2018/02/14 14:54:17 [error] 1521#0: *14 upstream timed out (110: Connection timed out) while connecting to upstream, client: 192.168.0.220, server: proxy.mydomain.com, request: "POST /service/soap/BatchRequest HTTP/1.1", upstream: "https://192.168.10.46:8443/service/soap/BatchRequest", host: "proxy.mydomain.com", referrer: "https://proxy.mydomain.com/"
2018/02/14 14:54:17 [error] 1521#0: *15 upstream timed out (110: Connection timed out) while connecting to upstream, client: 192.168.0.220, server: proxy.mydomain.com, request: "POST /service/soap/BatchRequest HTTP/1.1", upstream: "https://192.168.10.46:8443/service/soap/BatchRequest", host: "proxy.mydomain.com", referrer: "https://proxy.mydomain.com/"

The first timeout happened when the the login screen switched to the Loading screen. Then it was just sitting for the next 4 entries.

I figured out the connection issues. It was UFW rules that were not consistent with IP changes that I made part way through the process. I'm going to assume the issues are resolved for now.
Thank you for the pointers DualBoot.
