Java HotSpot(TM) 64-Bit Server VM warning

Question

I have a tomcat as my web-server, it stopped down automatically with the given Error -

Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00007         


        

Answer 1

There is insufficient memory for the Java Runtime Environment to continue.

Native memory allocation (malloc) failed to allocate xxxxx bytes for committing reserved memory.

Possible reasons:
1. The system is out of physical RAM or swap space
2. In 32 bit mode, the process size limit was hit

Possible solutions:
1.Reduce memory load on the system
2.Increase physical memory or swap space
3.Check if swap backing store is full
4.Use 64 bit Java on a 64 bit OS
5.Decrease Java heap size (-Xmx/-Xms)
6.Decrease number of Java threads
7.Decrease Java thread stack sizes (-Xss)
8.Set larger code cache with -XX:ReservedCodeCacheSize=
