HI,
I create a (temporary) queue and an object to store message data to my
database. This usually works well. However, whent I subject it to heavy(?)
load, I get errors like this:
| 2005-12-21 09:31:42,477 INFO [STDOUT] [ JMSLogger:: sendMessage: Exception

|
The only way to fix this seems to be to restart JBoss.
Does anyone know what is happening?
This is the code I use to test my queue:
| int repeat = Integer.parseInt(request.getParameter("repeat"));
| String logType = request.getParameter("logtype");
| if (logType != null && logType.length() != 0) {
| for (int i = 0; i < repeat; i++) {
| Class c = Logger.class;
| Class[] parameterTypes = new Class[] { String.class,
String.class };
| Method logMethod;
| Object[] arguments = new Object[] { "short" + i, "long"
+ i };
| logMethod = c.getMethod(logType, parameterTypes);
| logMethod.invoke(logger, arguments);
| }
| }
|
Thank you,
