Known Issues

Serial Version UID Mismatch

A Serial Version UID Mismatch Issue may be encountered if you deploy an application on a latest JVM, but compiled with an earlier JDK release.

Workaround: To be compatible with the serialization of previously compiled applications, modify the <BEA_HOME>/wlserver_10.0/common/bin/commEnv.sh file to include the following command:

JAVA_OPTIONS="$JAVA_OPTIONS -Dcom.sun.xml.namespace.QName.useCompatibleSerialVersionUID=1.0"

Note: If you intend to deploy new applications with previously compiled applications, they must be recompiled as necessary to have the same Serial Version UID.

Issues Related to Red Hat Enterprise Linux 5.0 on AMD64 and 64-bit Xeon

This section describes known issues that occur when you run WebLogic Server 10.2 on Red Had Enterprise Linux 5.0 systems based on the AMD64 and 64-bit Xeon chip architecture.

JVM Stack Overflow

You might encounter a JVM stack overflow error or exception while running WebLogic Server.

Workaround: Increase the stack size from the default 128k to 256k.

Exception Encountered on Systems with Mounted NFS File Systems

You might encounter the following exception while installing WebLogic Server and WebLogic Portal on a system that has NFS file systems mounted:

"Caused by:  java.lang.IllegalArgumentException: Can not list file system roots on this computer"

Workaround: Ensure that you have at least 600MB of free disk space before installing WebLogic Server and use the -Dspace.detection=false flag while installing. For example: 

java -Dspace.detection=false -jar server100_generic.jar -mode=console
