Does anyone use AWE memory for bufferpools in production environment?

I have instance crashes each time in the moment when all applications
disconnected from DB.

Diaglog has next info:

2004-07-14-07.00.53.484000 InstanceB2 Node:000
PID:1524(db2syscs.exe) TID:1640 Appid:*LOCAL.DB2.00D5C2120720
SQO Memory Management sqlofmblkEx Probe:24 Database:OLAP4

The pool that owns memory block 0x01EAE760 has already been freed!

That's why I suspect something wrong with bufferpools.

Could some help me?
