Tomcat hanging on a logging statement
I have a Struts web application that periodically hangs on a logging
statement.
The application hangs on this line
DynaActionForm loginForm = (DynaActionForm) form;
String username = loginForm.getString("username");
String password = loginForm.getString("password");
String redirect = loginForm.getString("redirect");
log.log(Level.INFO, String.format("Logging in user
'%s'", username));
// username is not null
My environment:
Tomcat 6.0.16
JVM 1.5.0_15 Sun
Windows XP
Has anyone else seen Tomcat hang on a logging statement? I removed this
logging statement, then after some time, the application hanged on the
next logging statement it encountered.
I also got a thread dump from the JVM, but I can't make much sense of it
