Linux下hs_err_pid.log错误Out of Memory Error

"Out of Memory Error"错误通常是由于进程尝试使用超出其可分配内存限制的内存而引起的。在Linux下，当进程使用超出其可用内存时，操作系统将向进程发送SIGSEGV信号，并将其杀死。

如果您遇到了这个错误，有几个可能的解决方案：

1. 增加可用内存：如果您的系统中有足够的物理内存和交换空间，可以尝试增加进程的可用内存限制。您可以使用ulimit命令来设置进程内存限制，例如：

ulimit -v <memory_limit>

其中，`<memory_limit>`是以KB为单位的内存限制值。

2. 优化代码：如果您的代码存在内存泄漏或其他内存使用问题，可以尝试优化代码以减少内存使用。

3. 升级硬件：如果您的系统中没有足够的物理内存和交换空间，可以考虑升级硬件来增加可用内存。

希望这些解决方案能够帮助您解决问题。

OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000d5580000, 715653120, 0) failed; error='Cannot allocate memory' (errno=12) # # There is insufficient memory for the Java Runtime Environment to continue. # Native memory allocation (mmap) failed to map 715653120 bytes for committing reserved memory. # An error report file with more information is saved as: # /opt/TongWeb7.0/bin/hs_err_pid2588233.log

This message indicates that the Java Virtual Machine (JVM) was unable to allocate enough memory for the Java Runtime Environment to continue running. The JVM attempted to allocate 715653120 bytes of memory, but was unable to do so due to insufficient memory on the system.

The error message also indicates that the JVM attempted to use the "mmap" function to allocate memory, but this operation failed. The error report file mentioned in the message may contain additional information about the error, including a stack trace that can help identify the root cause of the problem.

To resolve this issue, you can try the following:

1. Increase the amount of memory available to the JVM by using the -Xmx JVM option. For example, you can set the maximum heap size to 2 GB by adding the following option to your Java command line:

   java -Xmx2g your_program

2. Check the system memory usage and see if there is enough free memory available.

3. Reduce the amount of memory required by your program by optimizing your code or reducing the size of input data.

4. If the problem persists, you may need to consider upgrading the hardware or adding more memory to the system.
