- gc overhead limit exceeded (memory issue)
- java.lang.OutOfMemoryError: Java heap space
- java.lang.OutOfMemoryError: PermGen space
- shutdown or Shutdown
- high disk watermark [*] exceeded
- Too many open files
- Errors 1 - 4 are due to insufficient RAM. Please increase memory allocation and restart.
- Error 5 indicates shutdown (reasons could be memory or disk issue or network issue)
- Error 6 indices insufficient disk space issue. Please increase disk space allocated.
- Error 7 occurs in Linux if the ulimit value is not set to maximum.
Error specific to
/opt/searchblox/elasticsearch/logs/searchblox.log for Linux:
- max virtual memory areas vm.max_map_count  is too low, increase to at least 
Increase map count using the command:
sysctl -w vm.max_map_count=262144
If this error is observed in index.log or status.log it is required to increase the ulimit.
- Check the ulimit using the command:
- Edit the limits.conf file using the command:
- Give the following in the file before the end of file
* soft nofile 100000 * hard nofile 100000 root soft nofile 100000 root hard nofile 100000
- Now you can check the ulimit value using the command:
- ulimit value should be 100000 or higher
- Please reboot after this change.
