Solution

- Check for the java maxmemory in the wrapper.conf file.
- Increase if the values are set to default as below:

wrapper.java.initmemory=512
wrapper.java.maxmemory=2048

- It is always a best practice to have double the values to the default ones for the java maxmemory or depending on the monitoring environment and message size/load, triple the value if required.
