from the log:
1. apisix.node_listen port is ok before been restarted, access.log
2. `prometheus.lua:920 no memory` in error.log
3. the prometheus can't scrape the `/metrics` from apisix for few hours
-------
the service monitor config
```
interval: "30s"
scrapeTimeout: "30s"
```
so, if the response too slow(maybe the metrics data too huge?), it will
timeout and lost the line in chart.
if the prometheus privileged process keep receiving the `/metrics` for
hours, all timeout => a high cpu usage => the livenessProbe/readinessProbe to
the apisix will affected, timeout (`context deadline exceeded (Client Timeout
exceeded while awaiting headersi`) => the container been restart
