Re: Handhelds on ONE mail server activate painfully slow (hours)

[ Edited ]

After several long days on the phone with RIM and no clue as to what is occurring I think I may have cracked the code and if my theory is correct, it's not a RIM issue.

 

I installed over half a dozen additional test boxes, using various iterations of 5.0.x and MAPI/CDOs. None of them would work. I tried reusing the original IP and I tried using the IP of servers known to work with no resolution to the issue at all. Finally, I tried installing on a server 2003 (32 Bit) machine and WHALLA!! communication was normal. This narrowed it down to the fact that there is an issue of communication between a 2008 64 bit box and this mail server which is 2003 SP2 32 bit.

 

I did some searching and came upon my old nemesis: Receive Side Scaling (RSS)

 

http://support.microsoft.com/kb/951037

 

We did battle with RSS a while back when we were having some backup problems and when I checked the status of RSS on the NIC in the problematic mail server it was still turned on whereas it is disabled on all the other mail servers.

 

I think I've got my suspect cornered, but I need to wait for an outage window tonight to go all Columbo on it....more to come...

if that is the cause, kudos to you.

I wonder how many others this snake has bitten

Re: Handhelds on ONE mail server activate painfully slow (hours)

SUCCESS!!!!

 

Turned off RSS in Device Manager under the Properties for the Network Card>Advanced. The mail server dropped 3 pings and after bouncing the BES servers everything responds normally. Talk about your needle in a haystack.

 

This issue shows it's head a lot on Broadcom Onboard NICs on Dell servers but isn't isolated to either.

 

So, in conclusion: If you have a 64 Bit BES server talking to a W2K3 SP2 32 Bit Mail Server and traffic is so slow you can't get activations to progress, verify that the mail server has RSS (Receive Side Scaling) disabled.

 

Thanks for walking through the various spots to look Knotty, and extra set of eyes always helps keep the wheels moving.

glad you stuck with it, looked at other options, and posted the solution here for others to see.
