Wildfly 10.1消耗所有核心

本文介绍了Wildfly 10.1消耗所有核心的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我们最近将我们的银行应用程序从java 1.6升级到1.8，将jboss 4.x升级到wildfly 10.1。We have recently upgraded our banking application from java 1.6 to 1.8 and jboss 4.x to wildfly 10.1.我们观察到java消耗了所有核心（10可以在机器上找到。We have observed that java consuming all the cores (10), available on the machine.有人可以说出原因是什么，通常使用jboss 4.x最大CPU利用率最多可达4个核心。Can someone tell what is the reason, normally with jboss 4.x max CPU utilisation was up to 4 cores.我是否需要为垃圾收集配置任何东西？Do i need to configure anything for Garbage collection?以下是（在进程消耗高CPU时添加）的结果Below is the result of (added on process consuming high cpu) ps -eLo pid，lwp，nlwp，ruser，pcpu，stime，etime，args | grep 3630ps -eLo pid,lwp,nlwp,ruser,pcpu,stime,etime,args|grep 3630以下是每个消耗高CPU的LWP的十六进制Below is the hex for each LWP consuming high cpu现在我已检查线程转储对于LWP 7914Now i have checked thread dumpFor LWP 7914 默认任务-7＃182 prio = 5

dump服务器没有稳定所以我们不得不恢复到jdk 1.6和jboss 4.我想知道jboss 4一切正常，现在我不是能够通过wildfly设置或我的应用程序或GC设置识别问题所在。Server not getting stable so we had to revert back to jdk 1.6 and jboss 4. And i wonder with jboss 4 everything working perfectly, now i am not able to identify where is the problem, with wildfly settings, or my application or GC setting.线程转储分析的链接 线程转储分析结果代码 KycPictureServlet@Overridepublic void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { ServletOutputStream out = null; FileInputStream fin = null; BufferedInputStream bin = null; BufferedOutputStream bout = null; try { String filename = String.valueOf(request.getParameter("fileName")); String folderPathId = String.valueOf(request.getParameter("folderPathId")); String kycDocPath = ""; System.out.println("Folder Path : " + folderPathId + " \t" + filename); if (folderPathId != null && !folderPathId.equals("null")) { kycDocPath = new StoragePathService().getStoragePathByPathID(Integer.parseInt(folderPathId)).getFolderPath(); } else { kycDocPath = new StoragePathService().getStoragePathByPathID(EkoDBConstants.KYC_FILE_UPLOAD_PATH).getFolderPath(); } String uploadFolderPath = kycDocPath; final String filetofetch = uploadFolderPath + filename; if (filetofetch.toLowerCase().endsWith("pdf")) { response.setContentType("application/pdf"); // response.setHeader("Content-Disposition", "inline; // filename=\"" + filetofetch + "\""); } else if (filetofetch.toLowerCase().endsWith("tif") || filetofetch.endsWith("tiff")) { response.setContentType("image/tiff"); } else { response.setContentType("image/jpeg"); } File uploadFolder = new File(filetofetch); if(uploadFolder != null && uploadFolder.exists()){ out = response.getOutputStream(); fin = new FileInputStream(filetofetch); bin = new BufferedInputStream(fin); bout = new BufferedOutputStream(out); int ch = 0; ; while ((ch = bin.read()) != -1) { bout.write(ch); } } } catch (Exception e) { e.printStackTrace(); } finally { if (bin != null) { bin.close(); } if (fin != null) { fin.close(); } if (bout != null) { bout.close(); } if (out != null) { out.close(); } }}以前有不是任何finally块，所以如果异常流没有关闭，第二件事我已经添加了额外的检查以检查文件是否存在然后只打开流。Previously there was not any finally block, so in case of exception streams was not getting closed, second thing i have added extra check to check if file exists then only open stream.之后进行更改不再有线程卡在该servlet上。After making changes no more threads getting stuck on that servlet.我已经进行了最新转储，发现一些奇怪的进程消耗了cpu而没有结束I have taken latest dump and found some weird processes consuming cpu and not getting end"C1 CompilerThread3" #8 daemon prio=9 os_prio=0 tid=0x00007ff8dc231000 nid=0x11b6 waiting on condition [0x0000000000000000] java.lang.Thread.State: RUNNABLE"C2 CompilerThread2" #7 daemon prio=9 os_prio=0 tid=0x00007ff8dc22e800 nid=0x11b5 waiting on condition [0x0000000000000000] java.lang.Thread.State: RUNNABLE"C2 CompilerThread1" #6 daemon prio=9 os_prio=0 tid=0x00007ff8dc22d000 nid=0x11b4 waiting on condition [0x0000000000000000] java.lang.Thread.State: RUNNABLE"C2 CompilerThread0" #5 daemon prio=9 os_prio=0 tid=0x00007ff8dc22a000 nid=0x11b3 waiting on condition [0x0000000000000000] java.lang.Thread.State: RUNNABLE我还配置了从OLD Jboss 4复制的GC设置Also i have configured GC settings copied from OLD Jboss 4在线程转储中我发现一些LWP正在消耗CPU并且没有结束In thread dump i have found some LWP which are consuming CPU and not ending"VM Thread" os_prio=0 tid=0x00007ff8dc1e9000 nid=0x11B411af runnable"GC task thread#0 (ParallelGC)" os_prio=0 tid=0x00007ff8dc01e800 nid=0x11a6 runnable"GC task thread#1 (ParallelGC)" os_prio=0 tid=0x00007ff8dc020800 nid=0x11a7 runnable"GC task thread#2 (ParallelGC)" os_prio=0 tid=0x00007ff8dc022000 nid=0x11a8 runnable"GC task thread#3 (ParallelGC)" os_prio=0 tid=0x00007ff8dc024000 nid=0x11a9 runnable"GC task thread#4 (ParallelGC)" os_prio=0 tid=0x00007ff8dc026000 nid=0x11aa runnable"GC task thread#5 (ParallelGC)" os_prio=0 tid=0x00007ff8dc027800 nid=0x11ab runnable"GC task thread#6 (ParallelGC)" os_prio=0 tid=0x00007ff8dc029800 nid=0x11ac runnable"GC task thread#7 (ParallelGC)" os_prio=0 tid=0x00007ff8dc02b800 nid=0x11ad runnable"GC task thread#8 (ParallelGC)" os_prio=0 tid=0x00007ff8dc02d000 nid=0x11ae runnable内存和GC设置JAVA_OPTS="-Xms4G -Xmx12G -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=512m -Djava.net.preferIPv4Stack=true -Dsun.rmi.dgc.client.gcInterval=1800000 -Dsun.rmi.dgc.server.gcInterval=1800000 -XX:-UseConcMarkSweepGC -XX:SurvivorRatio=6 -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintGCDateStamps -Xloggc:/data/eko/GC.log -verbose:gc -XX:NewRatio=2"推荐答案可悲的是，我神奇的水晶球坏了，所以我们必须得到我们的用线程转储脏手。 首先，我们需要弄清楚，什么线程导致了Cpu加载，因为app服务器不是单线程的。假设你在Linux上，你可以使用标准的 ps 获取每个进程线程的cpu使用情况的详细信息：Sadly, my magical crystal ball is broken, so we will have to get our hands dirty with thread dump.First, we need to figure out, what thread is causing the Cpu load, as app server is not single-threaded. Assumimg you are on linux, you can use standard ps to get details of cpu usage per process thread: ps -eLo pid，lwp，nlwp，ruser，pcpu，stime，etime，args | grep [PID_OF_YOUR_WILDFLY_PROCESS]> unixthread.txt这里我们对列 nlwp lwp和pcpu感兴趣。查找具有最高cpu负载的线程。 接下来我们需要java线程转储：在高CPU负载期间获取线程转储：Here we are interested in columns nlwp lwp and pcpu. Find the threads with highest cpu load.Next we need java thread dump: Obtain a thread dump during the period of high CPU load: jstack -l [PID_OF_YOUR_WILDFLY_PROCESS]> jstack.out现在对于一些线程搜索：说你的unixthread识别出一个以nwlp 9999作为CPU hog的线程，将数字转换为hex- 0x270F并在jstack.out文件中搜索此值。它应该匹配一个java线程，堆栈跟踪应该可以帮助你查明问题。And now for some thread hunting: say your unixthread identified a thread with nwlp 9999 as the CPU hog, convert the number to hex- 0x270F and search for this value in your jstack.out file. It should match a java thread, with stacktrace that should help you pinpoint the problem.如果它与GC相关，那么继续堆转储以确保它不是泄漏在您的应用程序中。 如果您进行分析并仍然认为这是jvm或gc设置的问题，您应该与redhat伙伴联系。我相信，如果你打算在RedHat堆栈上运行一个银行应用程序，那么你肯定应该支付带有付费支持的EAP7，而不是支持Upstream OS项目的hazzard，而不支持最终的错误或问题。If it is GC related, then proceed with heap dump to ensure it ia not a leak in your app.If you do your analysis and still think it is an issue with jvm or gc settings, you should get in touch with redhat guys. I believe, that if you intend to run a banking app on RedHat stack, you should definitely go for EAP7 with paid support and not hazzard with Upstream OS project without support for eventual bugs or issues. 这篇关于Wildfly 10.1消耗所有核心的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
