Informix问题求教，让我很头疼！
大虾们：小弟一套环境：SUN Solaris 10 SPARC + Informix IDS 7.31.UD8
Informix启动后，运行大约一天日志就开始疯狂报错，
17:23:51listener-thread: err = -27001: oserr = 0: errstr = : Read error occurred during connection attempt.
17:23:52listener: poll return with non T_LISTEN/T_DISCONNECT event
17:23:52listener-thread: err = -25573: oserr = 13: errstr = : Network driver cannot accept a connection on the port.System error = 13.
17:23:53listener: poll return with non T_LISTEN/T_DISCONNECT event
17:23:53listener-thread: err = -25573: oserr = 13: errstr = : Network driver cannot accept a connection on the port. System error = 13.
17:23:54listener: poll return with non T_LISTEN/T_DISCONNECT event
数据库状态正常，而已经连上的应用也正常，就是无法建立新连接。连DBACCESS都连不上。
查了一下，oserr=13是Permission Denied，在网络操作时发生Permisson Denied，请问这个问题会发生在哪里？
帮小弟分析一下吧，非常感激！！

The first recommendation would be to upgrade off an old, no longer
supported version of IDS onto something more recent - like 10.00.
Presumably, you are not using new system - this is an old system that
has been working for ages.
This appears to occuring at about the time you're booting IDS - what
did you change in the Solaris environment to make it break?
If you are using a new system, why on earth did you install such an
old version of IDS? 我想你应该查以下你的操作系统方面的问题.
SUN Solaris 10 SPARC网络服务方面和以前的版本有很大的变化
[ 本帖最后由 tangmei958 于 2007-8-21 08:56 编辑 ] 执行dbaccess是什么用户，是不是该用户就没有操作数据库的权限。 ONCONFIG中有两个地方可以改一下试试：
1、NETTYPE：NETTYPE tlitcp,6,70,NET，同时建议把NETTYPE ipcshm,1,100,CPU这一项注释掉。
2、BUFFER：现有的配置是不是小了一点。如果内存还有空余，这个可以加一下。
