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
