jvm-crash

问题 We are seeing the JVM getting crashed at times with segfault. The only error we see in logs is as below. Anyone can suggest something by looking at the below error trace. # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x00007fef7f1d3eb0, pid=42623, tid=0x00007feea62c8700 # # JRE version: OpenJDK Runtime Environment (8.0_222-b10) (build 1.8.0_222-b10) # Java VM: OpenJDK 64-Bit Server VM (25.222-b10 mixed mode linux-amd64 compressed oops) #

问题 I had a tomcat crash on live server , which generated hs_err_pid file .In this there is a Problematic frame -> _wordcopy_fwd_dest_aligned+0x54. I searched in all similar cases of jvm crash but couldn't find whats the meaning of this problematic frame.Any suggestions ? # # A fatal error has been detected by the Java Runtime Environment: # # SIGBUS (0x7) at pc=0x00007f61087e3cb4, pid=18886, tid=140051814115072 # # JRE version: 6.0_37-b06 # Java VM: Java HotSpot(TM) 64-Bit Server VM (20.12-b01

问题 Given the following file lock request: FileLock lock = null; try { lock = randomAccessFile.getChannel().lock(0, Long.MAX_VALUE, mode.shared); // work with file } finally { if (lock != null) { lock.release(); } } The targetted OS being MS Windows, is there any chance the finally block won't be ever executed, and thus the lock never released? For example, what if the JVM crashes? How to handle such a no-owner-lock? 回答1: When the process exits, any OS automatically releases all resources

问题 We are developing multi-threaded java application using licensed Leadtools SDK 20 for converting large pdf documents to searchable pdf documents. During OCR process Java Virtual Machine randomly crashes - EXCEPTION_ACCESS_VIOLATION(Problematic frame: C [Ltocrx.dll+0x2af3a]). I've noticed that it may happens if user try to cancel OCR process. public class OcrProgressCallback implements OcrProgressListener { @Override public void onProgress(OcrProgressData ocrProgressData) { if (ocrProgressData

问题 I run a lot of java code on my servers, and occasionally I get a JVM crash, accompanied by a crash dump hs_err_pid file. Lately I've decided to try to be a better netizen, so I examined the latest crash log, made sure it was indeed the latest JVM, and that the crash was not caused by an external library, and then I tried submitting the file to Sun's bug database. However, it seems that the entire submitting process is geared towards preventing you from submitting bug reports, making sure you
