Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000e2a00000, 84934656, 0) failed; error='Cannot allocate memory' (errno=12)

今天打开网站，突然发现昨天还能正常访问的项目突然不能访问了，查看tomcat日志发现报如下错误：

Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000e2a00000, 84934656, 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 84934656 bytes for committing reserved memory.
# An error report file with more information is saved as:
# /data/tomcat/bin/hs_err_pid17188.log

 

经查证是java虚拟机内存溢出，修改JVM内存参数即可！
