对于数据量大的数据库，处理可能会需要更多的时间，因此有可能需要更改machine.config文件中processModel的responseDeadlockInterval 属性，比如为5分钟，默认为3分钟。
<processModel
enable="true"
timeout="Infinite"
idleTimeout="Infinite"
shutdownTimeout="0:00:05"
requestLimit="Infinite"
requestQueueLimit="5000"
restartQueueLimit="10"
memoryLimit="60"
webGarden="false"
cpuMask="0xffffffff"
userName="machine"
password="AutoGenerate"
logLevel="Errors"
clientConnectedCheck="0:00:05"
comAuthenticationLevel="Connect"
comImpersonationLevel="Impersonate"
responseRestartDeadlockInterval="00:09:00"
responseDeadlockInterval="00:05:00" default is 00:03:00
maxWorkerThreads="25"
maxIoThreads="25" />
