SocketException BEA-101083 Weblogic 9.2

Question

Hi,
we are facing a problem in our production environment, we get pratically every minutes the following exception :
<30 juin 2008 10 h 27 CEST> <Error> <HTTP> <BEA-101083> <Connection failure.
java.net.SocketException: Error in poll for fd=287, revents=32
     at weblogic.socket.PosixSocketMuxer.processSockets(PosixSocketMuxer.java:133)
     at weblogic.socket.SocketReaderRequest.run(SocketReaderRequest.java:29)
     at weblogic.socket.SocketReaderRequest.execute(SocketReaderRequest.java:42)
     at weblogic.kernel.ExecuteThread.execute(ExecuteThread.java:145)
     at weblogic.kernel.ExecuteThread.run(ExecuteThread.java:117)

What can be the cause of this ? Our users are telling us that the application goes very slow and this is the only abnormal log that we found.
Thank you,

Answer 1

Hi, the problem happens pratically once or two per minute while the application is in use... when the application is not used, no error happens.
So it happens very often... I thought it could be a problem with a proxy/firewall in the middle, but according to the guys in charge of this, nothing has changed on his side.
I've read things about a possible bug in the nativeIO implementation, would it be safe to deactivate nativeIO to see if this bug arise with pure java socket ?
Also this problem only occurs in our production environment, we have 4 others environment used for testing/training/integration and this error does not occur there.
Thanks for any help,
