group似乎有问题。只能新发帖回答。
我有几个问题需要你确认，然后才能给你建议。
1.get_first_data是你的函数还是net-snmp的函数。
2.死循环是在所有的节点上都会发生，还是只和特定节点发生。换句话说，如果提高get的频率，是否每个节点都会死循环。

谢谢sky
1.get_first_data是你的函数还是net-snmp的函数。
这个是mib2C产生的函数，输入net-snmp的函数了。

2.死循环是在所有的节点上都会发生，还是只和特定节点发生。换句话说，如果提高get的频率，是否每个节点都会死循环。

循坏的问题找到了，是部分节点的问题，也不是死循环，是因为我相应的操作花的时间比较长，所以返回timeout，我试着在
get_first_data处控制调用的次数，这个问题出现的次数就减少了。

但是我有个疑问，为啥我在调用上一个表的时候，同时也会调用下一个表呢，按理说这两个表是没有关系的。我也曾重新mib2c，但是问题依然一样的。
您是否遇到类似的问题呢，请帮我分析一下！

如果是这样那么还是要试着优化你的操作时间，又或者可能需要重新设计一下MIB，因为NETSNMP本身的超时阀值应该是一个比较通用的值。
get_first_data是MIB2C产生的函数，那么你把MIB2C产生的代码贴上来我看看吧。
