yes....at first i have contacted with them ...they just suggest me to change the os version...
Probably because you had an old ROS version. As you can read from changelog there are some ospf bugfixes in latest version.
IF you still have issue with latest version, generate supout again and send it to them with detailed description of your problem.

It's not possible to run 2.9 on RB333. There are no 2.9 PPC version.
