Hi All

Ok, so we've got about 80 users configured, not all connected at once, majority running IMAP with a few on KOC, BESX is patched in on another physical server with about 5 people configured on that - however, every now and then at random points during the day our system gets hammered and slows down - looking at the traffic logs its massive amounts of HTTP connections - although we've restricted the simultaneous amounts of connections to 150.

What are your theories to whats causing it and is there a way to find out if its a user, hacking attempt or something else? What do I need to look for in the logs?

Any one got any clues on this?


There seems to be a pattern (if you look at the 30 day chart), Monday to Friday. Doing some tests, sending large attachments causes spikes to appear in the connections chart - bigger the attachment, bigger the spike.

2 questions...

Is it possible to log the connections anywhere within KC?

Is KC counting the connections incorrectly, ie, if a file is still uploading or sending (large file), is it incrementing a count rather than realising the same connection is still active?

In the debug log, you can switch on

- HTTP server
- Kerio Blackberry Connector
- Network connections and SSL

You have to play around with those settings.
