Subject RE: Problem using SMTPAppender
Date Wed, 18 Feb 2004 17:15:11 GMT

Using AsyncAppender, the application does not block now.

 How can I know if the SMTPAppender had any problems while connecting to
the smtp host ? 
 For example, if I set up wrong host name in SMTPHost attribute for
SMTPAppender, is there any exception thrown when SMTPAppender actually
tries to send a message ?

Thanks in advance.

Regards
Mandar

For logging performance, but not for your application server.  I would
recommend setting it up with the async appender and seeing if you find
any noticeable degradation.

Hi Jonathan,
 Thanks for your reply.
 
Log4j documentation mentions that AsyncAppender might actually
significantly degrade performance. So, I am looking for other options.

Thanks
Mandar

 Connect SMTP appender to ASYNC appender.  This will stop the STMP
appender from blocking other processes.

Hi,
  I found this problem while using logger.error in exception block
 
JBoss 3.2.0
RedHat 8.0 / 9.0
Using log4j that is shipped with JBoss 

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. 

Any ideas on how to solve this problem ?

Thanks
Mandar
