Connection Resets from F5

Hi Hank

Please try the following.

1. Have you tried a packet capture, to show you where the reset is coming from?
2. Also, check persistency and SNAT/Automap settings.
3. create a new TCP profile and modify accordingly and apply to your vip.
4. The Fast L4 profile had fixed this issue for me.
5. Collect network traces on client side & server side simultaneously and compare.

a packet capture will defs point you in the right direction as well as a dump of your

If you willing you can skype me and i can try assist you with this.

Hi Lutha, thanks for your fast reply. I already had an support ticket for this case. We couldnt find a solution yet. I updated the severity at the highest now, because Exchange iApp is running so, sooo bad in our environment. I tried everything, googled everything. No solutions yet. There are alot of customers who are not able to work the last days. At first everything was running fine, but now we have such a poor perfomance, that 2010 clients can't even login OWA. Always "ERROR_CONNECTION_RESET".

We checked everything, it is just the external services from exchange. If I access internal URL, everything is fast and stuff. I dont know what has happened.

btw to your response:

1. Yes. Clients take like 10 sec or more after hitting login to reach slow OWA or error blank page

    

2. I checked, must be working.

    

3. Dont know what exactly I have to change. Played with intervals, sizes, nagle, delayed acks.. no success.

    

4. Could U explain me where I can find that Fast L4 profile?

to 5. I did and already checked with support.

1. Could U explain me where I can find that Fast L4 profile?

You can find it in TCP profiles

Hi Lutha, thanks. Today the issues are gone. We didn't changed anything. Yesterday everything was slow, today activesync + owa is working fine. We cant explaint it.. Maybe the slow perfomance issues happen in another place?
