操作数组导致的宕机

导致服务器crash的错误堆栈信息如下：

# thread  45/85  :: http pid=229630, k-id=unning  2, pthr-id=11309

# stack          :: k-state=wait, stk max-size=262144, cur-size=30156

根据服务器crash的堆栈信息，得到可能有如下两种情况使得服务器crash：

 

Ø         Domino服务器版本本身的Bug导致

具体信息可以参照IBM技术网站上的文档说明，需要将Domino的版本更新到7.0.2才能修复该问题

Title:    Server crashes on either Agent Manager or HTTP task in UnLinkDynArray function  Doc #:  1246804

URL: 

 

Ø         在代理程序中将操作数组函数作为另外一个函数的参数来处理会导致同样的问题，如下样例：

Call func1(Arrayunique(var1))

 

解决办法可以将代码进行调整

Dim var2 as Variant     

var2 =  Arrayunique(var1)

Call func1(var2)  

 

后来按照下面这种方式调整代码，到目前没有出现宕机。
