Current system mode is read-only

This means meeting error when flushing data to disk.

You could search "change system mode to read-only" in the error log to see what happened.

Some common reasons:

- Disk space is full
- Too many open files
- OOM

If OOM, two ways:
(1) config manually if you use 0.10 or earlier version:

conf/iotdb-engine.properties:
enable_parameter_adapter=false
tsfile_size_threshold=100000000
memtable_size_threshold=JVM memory/2/storage group number/4

(2) upgrade to version 0.11.2 or a later version
Generally, in 0.11 version, you do not need to config manually. If still OOM, you could still try to config

conf/iotdb-engine.properties:
enable_mem_control=false
tsfile_size_threshold=100000000
memtable_size_threshold=JVM memory/2/storage group number/4

If still OOM, lower the memtable_size_threshold!
