1. Add both of the following Generic JVM Arguments in the WebSphere      
Admin Console:                                                           
                                                                         
-Xtrace:none -Xtrace:maximal=mt,methods={com/ibm/jsse2/SSLSocketImpl.<init>} -Xtrace:trigger=method{com/ibm/jsse2/SSLSocketImpl,jstacktrace} -Xtrace:stackdepth=25,output={sslsockettrace,50m} -Xdump:system:events=systhrow,filter=java/lang/OutOfMemoryError                                        
                                                                         
The use of -Xtrace:none at the beginning turns off the default Java      
trace, which can be verbose. This allows us to see the java stack traces 
we want more clearly in the trace file.                                 
                                                                         
2. This setting is expected to produce a binary trace file named         
sslsockettrace. Once the OOM has been reproduced, please format the      
binary trace created from the argument above by issuing the following    
command from the WPS install root/java/bin directory. Here's an example: 
                                                                         
D:/IBM/WPS/java/bin/java com.ibm.jvm.format.TraceFormat sslsockettrace  
                                                                         
3. Then send in the formatted file, which will be named:                 
                                                                         
sslsockettrace.fmt
