Had some trouble with this, as PAM and root user restrictions obfuscated the setting. Here's the bug report:

https://bugs.launchpad.net/ubuntu/+source/pam/+bug/65244

Problem was that I set the value in limits.conf but PAM was not honoring it for ssh sessions. Then I used the * wildcard which was not honoring the value for the root user. The ejabberd user did have the proper ulimit applied.

I've increased ulimit to

I've increased ulimit to 2048, but problem still exist, than i've increased to 8192... but ejabberd still crashe..

# ulimit -n
8192

We are running jabber on company with nearly 50-60 employees;
Until migration to shared roster the ejabberd never crashes

You are running out of file descriptor. Increase your ulimit.

What could be the problem (file limit is not possible, because ulimit is "unlimited")?

To know the maximum number of allowed file descriptors, you must run 'ulimit -n':
