暴力重启DB2后，db2 connect to databasename,db2 restart都提示如下：
DB21016E  The Command Line Processor encountered a system error while sending
the command to the backend process.
DB21018E  A system error occurred. The command line processor could not
continue processing.
执行db2stop force、db2start 后，db2diag.log日志如下，数据库始终连不上:
