SocketAppenders

[Ganapathi Raman <ma...@yahoo.com>]

Hi...

I posted this Q last week but think it was lost...can
anyone please...


This is regarding socket appenders in general.

I am having an application that logs messages thru a
SocketAppender. I am using log4j's ServerSocket app as
a listener to receive the messages over the network
and log them. My question is that sometimes(only
sometimes and not all the time) i lose my
messages when at the server end (SocketServer) i get
error messages as :


20   [main] ERROR org.apache.log4j.net.SocketNode  -
Could not open ObjectInputStream to
Socket[addr=localhost/127.0.0.1,port=1638,localport=20200]

        at
org.apache.log4j.net.SocketNode.run(SocketNode.java,
Compiled Code)
        at java.lang.Thread.run(Thread.java:479)



I tried several times and am not able to get a pattern
that generated the error. Is it an error in the
network or am i screwing something up?

Can anyone help me??

Regards,
Ganapathi.
