This is pretty similar to that in 4052751, however, with different OS and different application running on top.

I do not know if we can produce a test case here since the problem occures
once in 100000 times with WebLogic running.

The problem is: java.net.SocketInputStream.socketRead throws
java.net.SocketException: Interrupted system call
The system configuration of the customer is:

SunFire6800 24CPU
memory 48GB
Solaris8 10/01
patch:Recommended Patch 4/29/2002
      109524-11
      108606-22
      108806-08
      110386-02
      111413-07
JDK1.3.1_04
WebLogicServer 6.1 SP3(WLS6.1 SP3)

The problem occures once in 100000 times.

The following is the stack trace.
