Tsave won't start

[BobiTo]

Hello, I have a very strange problem.
After starting tsave I see this:

NetUP UTM tsave: creating lock file ...
Collector none or netflow
NetUP UTM tsave: deleting lock file ...
Starting traffic.tmp parser!

And that's all!
I try to see eventually if the database is broken , but there was no error in it.

Anyone have an idea what's the problem?

I found what was the problem - if anyone else experience such thing to know: the file 'main' is missing. Simply copy it to utm/bin directory.
