[SOLVED] remote.connect_failure

[rhirsch]

Hi

I have installed Zimbra 6.0.8 on Ubuntu 10.04 LTS server.

Everything seems to be working but I get the message remote.connect_failure on the logon screen of the web interface. The failure is occurring every 3 to 4 hours. I restart the zimbra services using zmcontrol restart and all continues to work for the next few hours.

I have read a few posts that seem to be having the kind of problems. I have tried all the suggestions with out any success.

Could this be a problem running on Ubuntu?

Any help would be appreciated.

Richard

same issue here how did you resolve this ?

[rhirsch]

I added these lines to the /etc/security/limits.conf file

root soft nofile 524288
root hard nofile 524288

I found this info at the following location

https://bugzilla.zimbra.com/show_bug.cgi?id=42870#c81

I hope this helps.

6.0.9 automatically adds these to /etc/security/limits.conf. Been dealing with same problem, and didn't really resolve until I made some adjustments to the Java heap size (6GB max; less is more sometimes) and MySQL's innodb cache size (increased in relation to the amount saved on Java).

UPDATE: Check out your open file limits for zimbra and root. To do this, type:

ulimit -n

Zimbra will probably yield 52488
Root will probably yield 1024

Change root's .bashrc by adding the following to the end of the .bashrc when logged in as root:

ulimit -n 524288

Same problem here with my UBUNTU/ZCS install.

What's the deal behind this issue?

If you mean 'what's the answer' then it's in this thread in the post above yours.

No.

If isn't ZIMBRA's fault (something like UBUNTU server protection), I would be very surprised to see such an issue on a non beta version of the software. I mean, let's not waste time fighting over something that can be fixed, at least that's my position as an open-source user of the product. I'll always try to contribute whenever I can.

But as a paid user of the product, I'd be pissed right now; like "did you ever install this?"

I'll always love ZCS anyway.

You need to add for both root and zimbra users. Should look like this at the end of /etc/security/limits.conf:

zimbra soft nofile 524288
zimbra hard nofile 524288
root soft nofile 524288
root hard nofile 524288

I won´t extend this but seriously, as yet another SysAdmin out there, I´m considering submitting myself to product QA on the next beta program. Is this on every updated UBUNTU/ZCS setup? I mean, for me the issue happened within hours of use. Nasty and consistent. I know people putting themselves on the line choosing ZCS over competing solutions.

I´m old enough not to jump too quick into conclusions on tech matters but once again, I´m surprised!

did you try my last suggestion?
