Openfire Java Out of Memory Error – Any solutions?-Collection of common programming errors
I have huge problem with openfire crashing every now and then because of the lack of memory. In java log i have following error log. however problems are
- Openfire is 32 bit and i cant run it as 64 bit.
- Because its only 32 bit max memory i can give to the openfire is 4GB.
- My system is very powerful with 32 GB RAM so i cant increase any more
- Only max 100 users are using the openfire but still cant seems to handle it
- I have run a cron jobs every 5 min to monitor this service and restart every now and then
any solutions on how to optimize open-fire for memory usage and stop it crashing ?
error log as below
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 140 bytes for CHeapObj-new
# 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=

Openfire is written in java and is not 32-bit specific. If you use a 64bit jvm, it will run in 64 bit mode and you can give it as much ram as you have. Try installing a 64bit jvm/jre
