Description Matt Fago 2007-03-08 16:03:35 UTC
Please describe the problem:
I had Evolution-Connector 2.8.3-1.fc6 successfully connected to our Exchange 2003 OWA server. Unfortunately, I was informed that I could no longer use Evolution (hence the 'blocker' severity) due to the network storm that it was causing. Evidently it was causing several authentications per second to be sent to the Exchange back-end, filling up the server's logs and causing network issues.

Steps to reproduce:
1. Configure Evolution to connect to Exchange OWA
2. Check mail


Actual results:
Works fine, but it is causing completely unreasonable network traffic to be produced. I have been forced to stop using Evolution-Connector until this issue is fixed.

Expected results:
Significantly less network traffic. Some of this is certainly due to the decision to interface to OWA (https causes more traffic than the few packets sent with IMAP), but this network storm does not happen to the same extent when using a web-browser to connect to OWA.

Does this happen every time?
Yes

Other information:
I can try to produce logs via E2K_DEBUG if that would help. I want to make sure this gets addressed in the next version of Evolution if it cannot be fixed sooner.

Two things here - are we talking about only bandwidth usage or lots of authentication tries?

In either case, we would need E2K_DEBUG logs.  If you can send separate logs, that would be really fine.  You can mask your server details in the log and attach it here.. or send them directly to me.

[I had forgotten about this and evidently didn't add myself to the CC list.]

Not really bandwidth, just lots of traffic of some sort. All over https, so hard to tell what it is.

How would you like me to get the logs (I recall there are several settings for E2K_DEBUG etc)?

Thanks,
Matt

Matt, i guess E2K_DEBUG=4 would be suffice.
