Webdynpro Binary Cache Problem

I am creating an HTML file and saving it to the binary cache like this:

		String inString = "<HTML>";
		inString = inString + "<HEAD><TITLE>blahblah</TITLE></HEAD>";
		inString = inString + "</HTML>";

		byte[] byteString = null;

		try
		{
			byteString = inString.getBytes("UTF-8");
		}
		catch (UnsupportedEncodingException e)
		{

			wdComponentAPI.getMessageManager().raiseException(e.getMessage(), true);
		}

		try
		{

			IWDCachedWebResource resource = null;

			if (byteString != null)
			{
			resource1 = WDWebResource.getWebResource(byteString, WDWebResourceType.HTML);
			resource1.setResourceName("ViewerLaunching.html");
			resource1.setAttachement(false);
			resource1.setReadOnce(true);
			}

			IWDWindow window = wdThis.wdGetAPI().getComponent().getWindowManager().createNonModalExternalWindow(resource.getURL(), "JavaViewer");
			window.setWindowSize(1, 1);

			window.removeWindowFeature(WDWindowFeature.ADDRESS_BAR);
			window.removeWindowFeature(WDWindowFeature.MENU_BAR);
			window.removeWindowFeature(WDWindowFeature.STATUS_BAR);
			window.removeWindowFeature(WDWindowFeature.TOOL_BAR);
			window.open();
			wdContext.currentContextElement().setJavaViewerWindow(window);

		}
		//catch (final Exception ex)
		catch (WDURLException e1)
		{
			//wdComponentAPI.getMessageManager().raiseException(new WDNonFatalException(e1), false);
			wdComponentAPI.getMessageManager().raiseException(e1.getMessage(), true);
		}

I am getting sporadic errors in the log file but not sure if it is a problem:

Hi,

check out following threads:

your stack trace shows some time out problems, try restarting your server, may be possible that your max users supported is reached, and server cannot full full more requests, thus leading to thees exceptions.

Thanks
