Default Email Delay

Please Login to Remove!

When I send a email to myself from my BB, the email gets delivered almost instantly in my outlook That means communication is good between BB to BES and BES to Exchange however I don't receive it on my blackberry for 20 to 40 minutes. We have noticed that this delay occurs mostly in the morning between 9AM till about 12 PM. We have monitored the performance on both exchange and BES servers and both servers are super quite at that time. We have also checked with our carrier who escalated the case to RIM. While I am still waiting to hear from RIM can someone help me with this and point me in the right direction?

thanks
JK

I had a similar issue with very slow deliveries to my BB. Normally the BB gets an incoming message 1-2 minutes before it even shows up on my outlook. Hit a stretch where messages would come through in clumps anywhere from 20 to 90 minutes later onto the BB. The fix was a reboot on our servers. According to my IT group the problem will randomly happen to a limited number of users and that is their signal that it's time to reboot.

trooperdjb,
did you get intermittent delays like us? For us it happens mostly in the morning then in the evening or at night everything is ok. We have already rebooted our BES server but we haven't rebooted exchange server yet. do you think a reboot of the exchange server is necessary?

thanks
jk

Moved - this seems to be a BES type question.

Get your BES admin to send you a PIN message from the BES. If the message arrives immediatly, it may shed some light. If they have more than one BES server, have them move you from one BES to the other. This could knock the cob webs loose so to speak.

In the afternoon, how fast is the email delivered to your BB?
Is this ONLY your BB or everyone on the BES?

The problem was resolved !!!
It turned out to be our dns server which was running low on memory. Once we increased RAM on it, the blackberries started working super fast.

thank you everyone for your help

That may be the most peculiar solution for BlackBerry email delivery I have ever heard of... Glad it's working.

It didn't make sence to us neither but somehow it's working. I don't know why exchange or BES server would rely so much on dns once they already know the IP address of each other? I mean that's what dns cache is there for ! The email delivery is instant now, we get it on our blackberries even before we see it in our outlook.

It might be because the TTL of RIM's servers are 10 minutes.

Feel free to add your own explanation on why a low-memory DNS server would cause this issue ;)

not responding to DNS queries ... AD / GC functionality relies on 100% reliable DNS functionality.

its really very simple.

I guess I've just never heard of someone having a production DNS server without adequate RAM. Certainly isn't the first time I'm sure.
