Is it just me or does zimbra seem a little unstable?

I'm using the open source addition. I had an older version running on Ubuntu 8.04. It worked until I tried to do an update. For some reason there were perl modules that wouldn't load. My fix was installing 6.0.5 on a clean Ubuntu 8.04 system and migrate my email over.

I tried uploading a csv file to create the accounts. It just gave me an error message. When creating accounts it stopped letting me type anything into the text box. Seems to be working now. That could have been something on my end. Don't know for sure.

I like the features in the web interface but it needs to be more stable if I'm going recommend it to others. Again, I'm posting this to see if anyone else had a bad experience.
