Those of you on 4.1.4 MR4 (Rollup) (Bundle 134), you should be able to contact RIM, state the severity of your issue and request the following two patch files -
BlackberryAgent.exe
BlackberryAgent.pdb
These two files, provided by RIM, resolved my issue (see my earlier post).
I don't know about you guys, but I'm a bit paranoid when it comes to applying change to my BES. I highly recommend you get the files from RIM and not be passing around files. I'm pretty sure RIM would be less then 100% helpful if your BES tanked after applying patches not provided by them.
Additionally, how else will they know to what degree this issue has impacted our messaging systems.
