Unhappy Message delay issue.

Please Login to Remove!

So here's the issue... I have a user who experiences a huge delay when

receiving emails. For instance if I send an email to him he sometimes has to

wait greater than an hour to receive. The weird thing is when he finally

receives it, he receives all the pending messages after mine aso. It's like he

is receiving emails in bunches. He is receiving a strong signal and others that

are using the same carrier are functioning normally. I am running BES

on Domino 6.5.4 FP2 any suggestions?

If all other users are receiving email messages normally and only this particular user has messages delay, then there must be something particular about this user's mail database.

Compare his mail database's size with that of another user. Is this very large? Also, did you recently restart the BES? If yes, then it could potentially worsen the situation as BES will RESCAN all mail databases after a restart. Imagine BES crawling through a 1 GB mail database... (Reference Source: KB-04789 What Is - Restarting BlackBerry Enterprise Server services may cause delays in message delivery)

Mail database corruption or huge whitespace could contribute to the issue as well. If mail database size is not the issue, try performing compact or even updall/fixup to be on the safe side as part of the troubleshooting.

RIM has an article describing factors that contribute to message latency (Reference Source: KB-01685 What Is - Factors that contribute to latency)

If all above exhausted, then you probably would want to get the RIM tech (if you have TSupport) to review the BES log to see if thread that serves the mail server related to this user is optimized. Sometimes a overloaded/hung thread may cause the delay too.

Good luck!

How many users on the bes are on the same mail server as this user? It could be that there are not enough threads. The server gives first priority to the oldest user, so if there are not enough threads the people at the top of the list will have better response than the end. You can increase the thread count.

Did anyone have a solution to this yet? I have the same issues and I'm using BES on Exchange 2003 SP2. I checked with RIM TSupport, they won't assist me because my network latency between the BES server and my exchange exceeded the 35ms. Please send me an email if you have any solutions to this.
