Hi Jonathan,
How do you connect SMTP appender to Async appender?
I would appreciate xml example.
Thanks.

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

Strange behaviour with JDBCAppender -- long time lags before control returns to code

[Frank Burns <fr...@the-hub.demon.co.uk>]

Hi,

Can anyone shed some light on what might be happening here?

I was using the JDBCAppender that comes with log4j 1.2.8 to perform logging
to database tables.

This worked well except if no logging events occurred for some time then the
database logging ceased. I believe this was because the connection to the
database was timing out.

In an attempt to cure this I used the JDBCAppender from Thomas Fenner and
updated by Danko Mannhaupt -- see .

This now works fine for my app running on my development linux installation,
where it is logging to a mySQL database located on the same machine.

However, on the live linux implementation, where the database is on a
different server, when no events occur for some time, the logging to the
database still takes place immediately (the timestamp logged in the database
shows this) BUT it takes up to FIFTEEN MINUTES for control to return to the
code following this logging statement

    successfulLoginLogger.info(username.toUpperCase() + " logged in.");

Any ideas what's happening and how to solve it?

Thanks.

Frank Burns.
