是想带启动和查询日志一起拿下来看一下么？
是的， 启动的时候的一些日志

这里还有一个很有意思的现象
机器内存 2C16G
测试水位线

–memory_tracker_limit_ratio=0.5
–memory_tracker_untracked_reserved_memory_mb=50
NGQL 1
MATCH p=(src)-[e:ScheduleTaskRelationship*10]-(dst) where id(src) in [1113869279948709888] RETURN DISTINCT p LIMIT 300；
正常执行会被打爆，15G+内存不足，OOM killed
执行日志
nebula-graphd.data-cdh6-test02.root.log.INFO.20230630-181510.9310 (64.8 KB)
NGQL 2

可以正常执行，在水位线设置再0.9的情况下，大概需要消耗12.xG的内存，运行完成。
但是水位线设置为0.5后，重启服务，也会在正常的8G+的时候被拦截，java客户端也会出现-2600错误码
拦截日志：
nebula-graphd.data-cdh6-test02.root.log.INFO.20230630-181007.8635 (121.3 KB)
客户端日志：
你好， 你这边先尝试在配置文件中改下max_job_size， 将默认值的1改成多个，比如改成2, 看能不能生效
–max_job_size=2
max_job_size=1的情况，我们会去修复；

当调整为2时，验证准确无误，可以拦截！谢谢快速支持，辛苦了！
