我这里主要存zabbix监控信息，使用了一个存储组，每1分钟存2000条时序数据，我应该调整哪些内存参数？我现在使用1台4核16G机器。
我修改了iotdb-env.sh中的配置：
half_system_memory_in_mb=`expr $system_memory_in_mb / 2`
quarter_system_memory_in_mb=`expr $half_system_memory_in_mb / 2`
if [ "$half_system_memory_in_mb" -gt "1024" ]
then
half_system_memory_in_mb="4096"
fi
if [ "$quarter_system_memory_in_mb" -gt "8192" ]
then
quarter_system_memory_in_mb="8192"
fi
if [ "$half_system_memory_in_mb" -gt "$quarter_system_memory_in_mb" ]
then
max_heap_size_in_mb="$half_system_memory_in_mb"
else
max_heap_size_in_mb="$quarter_system_memory_in_mb"
fi
MAX_HEAP_SIZE="${max_heap_size_in_mb}M"
# Young gen: min(max_sensible_per_modern_cpu_core * num_cores, 1/4 * heap size)
max_sensible_yg_per_core_in_mb="200"
max_sensible_yg_in_mb=`expr $max_sensible_yg_per_core_in_mb "*" $system_cpu_cores`
desired_yg_in_mb=`expr $max_heap_size_in_mb / 4`
if [ "$desired_yg_in_mb" -gt "$max_sensible_yg_in_mb" ]
then
HEAP_NEWSIZE="${max_sensible_yg_in_mb}M"
else
HEAP_NEWSIZE="${desired_yg_in_mb}M"
fi
请问这个问题如何解决？

另外，./memory-tool.sh calmem -sg 1 -ts 432000，这个 -ts 指的是时间序列数量，432000是实际的数据点个数，不是一个维度的。几万时间序列的负载一般都不需要计算这个内存，系统内部会自动调整

应该是做了错误的元数据操作，0.9.3 版本修复了这个启动问题，可以升级到 0.9.3

路径最后一层存在特殊字符，比如 [/.s1]，而且没用双引号括起来，启动时候跳过了这些错误的日志，没有影响服务器启动。
路径最后一层如果想有多个 . 和特殊字符，可以用双引号括起来，不过所有insert、select查询都需要把最后一层括起来，下面这种是可以的：
create timeseries root.host_item_test."vfs.fs.size[/,free]" with datatype=FLOAT, encoding=RLE, compression=SNAPPY
insert into root.host_item_test(timestamp,"vfs.fs.size[/,free]") values(1,1)
select "vfs.fs.size[/,free]" from root.host_item_test
