当我用OpenOffice将大量文件转化成PDF的时候，soffice.bin进程的内存持续增大。当到一定程度的时候soffice.bin进程就挂了，转换失败。每次转换完一个文件后我都执行了XComponent对象的dispose方法。为什么它的内存会会不断增长呢？

以下是转换方法：

public static void fileconverter(XComponentContext xContext, int min, int max)
{
PropertyValue[] propertyValues = new PropertyValue[1];
propertyValues[0] = new unoidl.com.sun.star.beans.PropertyValue();
propertyValues[0].Name = "Hidden";
propertyValues[0].Value = new uno.Any(true);

unoidl.com.sun.star.beans.PropertyValue[] propertyValue2 =
new unoidl.com.sun.star.beans.PropertyValue[2];
propertyValue2[0] = new unoidl.com.sun.star.beans.PropertyValue();
propertyValue2[0].Name = "Overwrite";
propertyValue2[0].Value = new uno.Any(true);
propertyValue2[1] = new unoidl.com.sun.star.beans.PropertyValue();
propertyValue2[1].Name = "FilterName";
propertyValue2[1].Value = new uno.Any("writer_pdf_Export");

for (int i = min; i < max; i++)
{
XMultiServiceFactory xMCF = (unoidl.com.sun.star.lang.XMultiServiceFactory)xContext.getServiceManager();

XComponentLoader xCompLoader = (XComponentLoader)xMCF.createInstance("com.sun.star.frame.Desktop");
string inputFile = AppDomain.CurrentDomain.BaseDirectory + "1.docx";
string sUrl = PathConverter(inputFile);
string outputDir = AppDomain.CurrentDomain.BaseDirectory + "Test" + i.ToString() + ".pdf";

XComponent xComponent = xCompLoader.loadComponentFromURL(sUrl, "_blank", 0, propertyValues);

string sOutUrl = PathConverter(outputDir);

int index1 = sUrl.LastIndexOf('/');
int index2 = sUrl.LastIndexOf('.');

((XStorable)xComponent).storeToURL(sOutUrl, propertyValue2);

xComponent.dispose();
}

}
