DB2 报错DIA3202C TCP/IP call connect returned an errno=78

数据库版本目前为db2 v9.1 for aix，最近系统中一直出现以下报错：

FUNCTION: DB2 UDB, common communication, sqlcctcpconnr, probe:110

MESSAGE : DIA3202CThe TCP/IP call "connect" returned an errno="78".

这是IBM DB2的一个bug，详细描述：

IC64525: SQLCODE -30020 OR DRDA DATA STREAM SYNTAX ERROR REPORTED BY DB2 CONNECT SERVER after a TCP/IP error is reported.
