无法正常启动代理内核

Expected Behavior

No response

Steps to Reproduce

配置文件里我设置了 50个分组 ，50个节点，貌似每个分组都加载了50个节点，导致缓冲区不足

Use alidns for China mainland domains and googledns for others.

dns {
upstream {
# googledns: 'tcp+udp://dns.google:53'
alidns: 'udp://119.29.29.29:53'
}
routing {
request {
fallback: alidns
}
response {
# upstream(googledns) -> accept
# ip(geoip:private) && !qname(geosite:cn) -> googledns
fallback: accept
}
}
}

报错信息如下:

0.8.0可以复现，但是main HEAD已经没有问题了。
