A bug in shmem_truncate_range can cause 100% CPU utilization.
This SLES10 GA problem can impact DB2 9 instances on all architectures. The shmem_truncate_range issue can cause a db2sysc process to appear as if it is hung and/or consume 100% of a CPU. It can also result in a kernel panic. On Intel Itanium hardware, symptom may include an unexpected system reboot. A fix will be available in SLES10 Service Pack 1. Until SLES10 SP1 becomes available, this problem can be prevented by setting a DB2 registry variable DB2MEMDISCLAIM=NO before starting the instance.
DB2 9 DPF incompatibility with SLES 10 and SLES 11 Randomized Virtual Address Space Mapping.
DB2 9 DPF instances with multiple logical partitions running on a single SLES 10 or SLES 11 server can trap within 30 minutes after db2start. If you are using DB2 V9.1 GA or DB2 V9.1 FP1, you must disable the memory mapping feature. Please refer to technote ref # 1251352
