???remote.CONNECT_FAILURE???

[holger]

Hi there,

yesterday I installed Zimbra FOSS in its latest version on a Ubuntu 10.04 server.

It's the third time this day that I try to login via webinterface (as a normal user) and get the message: ???remote.CONNECT_FAILURE???

Because I'm not so familiar with the Zimbra-Ecosystem yet, I restart Zimbra via "/etc/init.d/zimbra" restart or "zmcontrol restart" everytime the error occurs. After that everything works fine, until the next "crash".

I'm not sure, which logmessage I should post here, so maybe this message from mailbox.log helps a little bit:

Please let me know, if I can give you further informations from other logfiles.

Thanks for your help,

The likelihood is you have a configuration issue, if you're behinf a NAT router then you should have a valid /etc/hosts file (check the Quick Start Configuration Guide for details) and a Split DNS set-up - do you have both of those set correctly? Go to to the article in the wiki for Split DNS and set it up (f you don't have it already) then go to the 'Verify ...' section of that article and post the output of the commands here for verification.

Im experiencing the same error.

(Soap Exceptions on 6.0.8_GA_2661.UBUNTU10_64)

Although im not in need of a NAT Setup.

Then for confirmation you should post the information I asked for in my previous post, the details required are in the 'Verify...' section of the Split DNS article.

[pge]

I've sent the info via PM.

Im seeing this as well, Zimbra FOSS on 10.04, it works for the majority of the time - note ive already fixed the ulimit problems previously seen. Im not using NAT, or split DNS, jus a standard set up.

A config problem would for me happen more often, unless im hitting some other kind of limit, but please note this does not happen when the server is at its busiest.

could be this:
Bug 51328 – LDAP connection leak
seems it's included in a "to-be-released" patch

This is what my mailbox.log sees during:

@holger, i have a different issue to you - apologies for hijacking this thread. Youre suffering from the ulimit issue, your fix is here:

zimbra 6.0.8 FOSS - Ubuntu 10.04 LTS - LDAP errors

[pge]

Affirmative. The raise of roots ulimit fixed the problems for me also.
