SocketException (Invalid arg) on Solaris

["Folbrecht, Paul" <PF...@starkinvestments.com>]

Running Tomcat 4.0.1 with JBoss 2.4.4 on Solaris 8 with Sun JDK 1.31.

We see this problem on a very sporadic basis - it appears from the trace
that perhaps Socket.setTcpNoDelay() isn't supported by this JDK, and Tomcat
is not prepared to handle that.

Anyway, there is a SocketException, and the reopen attempts fails.  I
suspect the reason for that is that either the socket was never closed or
for some other reason the OS is still has the port locked.

Anyway, the end result is that after this event the server no longer accepts
HTTP requests, obviously since the listener socket is dead.  The JBoss
console, however, can still be served at port 9082.

Haven't been able to find anything in the docs to explain this.  If someone
knows a workaround- including a version upgrade- please let us know.  TIA.
