如何配置tomcat 6，以便如果它因内存不足而崩溃，我会收到堆转储？

Answer 1

您应该在tomcat6/bin/catalina.sh：

的开头（评论后）添加以下行

JAVA_OPTS="$JAVA_OPTS -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/path/to/dir"

文件： http://www.oracle.com/technetwork/java/javase/tech/vmoptions-jsp-140102.html

-XX:HeapDumpPath=./java_pid<pid>.hprof  Path to directory or filename for heap dump. Manageable. (Introduced in 1.4.2 update 12, 5.0 update 7.)
-XX:-HeapDumpOnOutOfMemoryError Dump heap to file when java.lang.OutOfMemoryError is thrown. Manageable. (Introduced in 1.4.2 update 12, 5.0 update 7.)
