在 linux 上执行jmeter 代码的时候遇到一个问题:There is insufficient memory for the Java Runtime Environment to continue.
报错内容在 windows 先执行过 get_info.jmx,正常运行,传到 linux 上运行时遇到以下问题
[root@VM_0_2_centos ~]# jmeter -n -t get_info.jmx -l get.jtl OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c0000000, 1073741824, 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 1073741824 bytes for committing reserved memory. # An error report file with more information is saved as: # /root/hs_err_pid25736.log
从报错可以应该是内存不够用了,free -m 查看内存
[root@VM_0_2_centos ~]# free -m total used free shared buff/cache available Mem: 3789 3295 152 12 341 179 Swap: 2047 2047 0
果然 free 内存只有 152 了
解决办法先清理掉一些不用的进程,释放一些内存出来,再次查看,大于1G,基本上没啥问题了
[root@VM_0_2_centos easymock]# free -m total used free shared buff/cache available Mem: 3789 2390 875 12 524 1084 Swap: 2047 1478 569
再次运行
