Pls see below Thread trace : "ExecuteThread: '33' for queue: 'weblogic.kernel.Default'" daemon prio=5 tid=0x30a8f0 nid=0x2d waiting for monitor entry [8fcfe000..8fd019bc] at org.apache.log4j.RollingFileAppender.rollOver (RollingFileAppender.java:126) at org.apache.log4j.RollingFileAppender.subAppend (RollingFileAppender.java:228) at org.apache.log4j.WriterAppender.append(WriterAppender.java:150) at org.apache.log4j.AppenderSkeleton.doAppend(AppenderSkeleton.java:221) - locked <b71560a8> (a org.apache.log4j.RollingFileAppender) at org.apache.log4j.helpers.AppenderAttachableImpl.appendLoopOnAppenders (AppenderAttachableImpl.java:57) at org.apache.log4j.Category.callAppenders(Category.java:187) - locked <b715d2d0> (a org.apache.log4j.Logger) at org.apache.log4j.Category.forcedLog(Category.java:372) Thread dump 1/4 " Thread-25402 <threadFilter.do?mode=ModeAllThreads&FullThreadIndex=0>" prio=5 tid=0x14f92d0 nid=0x638b waiting for monitor entry [8a301000..8a3019bc] at org.apache.log4j.Category.callAppenders(Category.java:185) - waiting to lock <b715d2d0> (a org.apache.log4j.Logger) at org.apache.log4j.Category.forcedLog(Category.java:372) at org.apache.log4j.Category.log(Category.java:864) Is there any know solution/patch for this error?
