Hi, I found this problem while using logger.error in JBoss log4j setup
JBoss 3.2.0 RedHat 8.0 / 9.0 Using log4j that is shipped with JBoss
In an EJB, I was using logger.error (that logs to a file and should send an email) on exceptions.
The machine did NOT have connectivity to our mail server. What was happening is the JBoss server used to hang for 3 minutes and 10 seconds every time the exception occurred. All clients had to wait till this time out expired.
The problem was resolved the moment I was able to connect to mail server from that machine.
I thought that even if one EJB instance is waiting for some event, other calls should go through.
