最近小型机有时会出现内存不足（在终端不能使用任何命令，老是报内存不足），但机子上只装了db2。
查看了下db2dialog.log，发现大量的S锁升级，日志如下，日志中对应的表只有查询操作

MESSAGE : ADM5500W DB2 is performing lock escalation. The total number of
locks currently held is "809", and the target number of locks to hold
is "404".
快照如下：
Locks held currently = 9
Lock waits = 85
Time database waited on locks (ms) = Not Collected
Lock list memory in use (Bytes) = 41984
Deadlocks detected = 0
Lock escalations = 2978
Exclusive lock escalations = 0
Agents currently waiting on locks = 0
Lock Timeouts = 0
Block IOs = Not Collected
Pages from block IOs = Not Collected
Internal rollbacks due to deadlock = 0
Number of MDC table blocks pending cleanup = 0
Memory Pool Type = Lock Manager Heap
这样的情况正常吗？？麻烦帮忙看看
