我有一个cfc方法，它正在循环遍历列表并通过cfhttp进行一系列SOAP调用。然后将结果插入到数据库中。
这个过程本身运作良好，问题在于Java内存会缓慢填满，并最终停止工作（具体取决于返回记录中的元素数量）。没有错误或任何可见的东西，它就会停止。如果我通过Coldfusion管理界面查看应用程序日志文件，我会看到以下一种或两种错误：
GC overhead limit exceeded The specific sequence of files included or processed is:
或者
Java heap space The specific sequence of files included or processed is:
以下是我正在运行的代码的简化版本：
<cfsetting requesttimeout="3600">
<cfloop condition="thisPass lt 10">
<cfscript>
runtime = CreateObject("java","java.lang.Runtime").getRuntime();
objSystem = CreateObject( "java", "java.lang.System" );
soapBody = '';
soapResponse = '';
thisStruct = '';
lock scope='application' type='exclusive' timeout='60' {
//This is where I am trying to manage the memory and call garbage collection
try {
freeMemory = runtime.freeMemory()/1024/1024;
writeOutput("- fm = "&freeMemory);
if (freeMemory < 200){
objSystem.gc();
sleep(1000);
writeDump(' - dumping freeMemory');
}
}
catch(any error) {
writeDump(' - trying to dump GC as '&now()& ' freeMemory = '&freeMemory);
}
}
</cfscript>
<cfsavecontent variable="soapBody">

<cfscript>
soapBody = "";
soapResponse = httpResponse.fileContent;
soapResponse = xmlParse( soapResponse );
thisStruct = xmlSearch(soapResponse,'/soap:Envelope/soap:Body/')[1].xmlChildren[1].xmlChildren[1].xmlChildren;
writeOutput("-"&arrayLen(thisStruct)&' records');
getPageContext().getOut().flush();
if(arrayLen(thisStruct) == 2500){
thisPass = thisPass+1;
} else {
writeOutput("- total records = "&(2500*(thisPass-1))+arrayLen(thisStruct));
thisPass = 100; // since looping while thisPass lt 10 this should prevent the next iteration
}
</cfscript>
<cfloop from="1" to="#arrayLen(thisStruct)#" index="i">

</cfloop>
</cfloop>
GC似乎有时会释放一些内存，但不可靠。我知道GC()只是建议Java释放一些未使用的内存，但我不确定如何强制其释放内存。可能存在某个泄漏，但我没有看到它。我希望这是一些明显的问题，我承认我的Java知识极其有限。
有没有什么Java大师能看到我的错误？
更新：以下是输出示例，以便查看内存下降是否有帮助。
