Insufficient memory for Java Runtime Environment to continue in Tomcat
I'm a tomcat/ tech newbie, so i'm sorry if I make any mistakes in the problem description.
I'm trying to run a dashboarding application, DOMO on our test server. We have been using tomcat to run the application since a decade, and everything usually works fine. Recently, when I tried to run the application, it wouldn't run. I cleared the work directory and tried to run tomcat again. Nothing worked and the application log for DOMO (the dashboarding tool) gave the following error:
Caused by: java.io.IOException: Insufficient system resources exist to complete the requested service
at java.io.WinNTFileSystem.canonicalize0(Native Method)

The system error log looked like this:
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 32744 bytes for ChunkPool::allocate
# Possible reasons:
# The system is out of physical RAM or swap space
# In 32 bit mode, the process size limit was hit
# Possible solutions:
# Reduce memory load on the system
# Increase physical memory or swap space
# Check if swap backing store is full
# Use 64 bit Java on a 64 bit OS
# Decrease Java heap size (-Xmx/-Xms)
# Decrease number of Java threads
# Decrease Java thread stack sizes (-Xss)
# Set larger code cache with -XX:ReservedCodeCacheSize=

I've read a lot of posts on related topics but since I have had an application running for the past decade, this issue popping up all of a sudden seems really bizarre to me. Also, this environment is like a test server and currently I'm the only one using it for dashboards. Hence, the possibility of system load having increased doesn't seem right; nor the possibility of a memory leak.
Can anyone guide me as to what might have gone wrong in this situation?
Thanks!
EDIT: I think my problem is different since its not some new chuck of memory to be allocated, but a ChuckPool:: allocate operation which suddenly stopped working even though no new load was introduced on the server.
Answer
What is the min and max heap size for the JVM? The out of memory error occurred due to low memory for JVM heap. What is the OS having Tomcat? Is it a 32-bit OS? Also, what is the RAM memory on the system?
32-bit OS with let's say 4GB or higher RAM, maximum JVM heap size could only be 1.5GB. So, adjusting your max and min heap memory size to 1.5 GB could alleviate the problem. Since you are sure there is no memory leak, you should look at choosing right kind of GC collector for your application -a throughput based GC or other (parallel, etc) and optimize pause times and collections. This would allow JVM to have enough room for new object allocations and not run out of memory.
