Recent Java applications, CPU usage has been very high, often up to 100%, through the following steps to solve the perfect, share.1.jps gets the PID of the Java process.2.jstack PID >> Java.txt Exports the thread stacks that the CPU consumes high processes.3.top-h-P PID to s

We use the jstack from the JDK to analyze it. When Linux CPU is consumed by Java programs, the following process might help you:1.top Find out which process consumes a high CPU21125 co_ad2 0 1817m 776m 9712 S 3.3 4.9 12:03.24 java5284 co_ad 0 3028m 2.5g 9432 S 1.0 16.3 6629:44 java21994 MySQL 0 449m 88m 5072 S 1.0 0.6

Using Tomcat as a Java container, the CPU occupies a high reason, the current company server running on the Ubuntu environment Nginx+tomcat+mysql run for some time after the Java process CPU high, will appear the site can not open the situation. So the following analysis is

1: View all process pid through the JPS command.2: Use top-p PID to view the CPU and memory and load of the process for the PID you are looking forUse top-p pid-h to view CPU-intensive queries for each threadIf you find that a certain PID CPU is too

Many people think that the higher the fan speed, then at the same time, the more heat away from the CPU, so that the more easily the CPU cooling, the fact is not so. If the fan speed exceeds its standard value, then the fan in a long period of overload operation, the heat away from the CPU than it in the high-speed ro

Today landed a colleague of the gateway began to think that the hive environment can not landing, a closer look at the next is because the machine is very card, I have to wait a few seconds without landing on the CTRL + C, see the next is a Java process cpu:340.4% mem:14.6%The general workaround is to use the top command to identify the high-resource thread ID an

address tags, this method brings a lot of problems, the process ID must be added to each row of data on the basis of the original tag to distinguish the same address among multiple processes, which is also troublesome for processing shared memory, there are different virtual addresses in different processes in the sharing, and how to synchronize them is a problem.Physical Index physical tagged Physical cache, physical index physical tagged, physical

How to use Jstack to pinpoint the exception code (Java program CPU utilization is high)Please jstack artifact to helpThis paper introduces the secret of using Jstack location problem in Linux environment.S1. "Top command" to find a process with high CPU utilization, get [

The cpu usage of the aix system is too high. We found that the cpu usage of oracle is too high today. As long as oracle is used on the machine, it should be caused by SQL statements, it is caused by SQL statements. The specific operation is as follows: the Java code ix command topas finds that the

two-byte alignment. By default, the common GCC compiler uses 4-byte align, which ensures that the first address of the thread lock attribute variable is a multiple of 4, when m68k is used for compilation, the _ align member cannot ensure that the first address of the thread lock attribute variable is a multiple of 4 (actually a multiple of 2 ).3.2.3 parameter error asking what causes high CPU usage Assume
