   > We also have similar issues. Currently, we have found that the pattern 
seems to be triggered with a very small probability when updating services in 
large quantities. The apisix ingress controller correctly updated the pod IP to 
etcd ,through curl XGET http://127.0.0.1:80/apisix/admin/upstream/xxx It is 
correct to check the IP list of Upstream, but there will still be a small 
number of requests made to offline IPs by Apisix until it is restarted to 
restore normal operations. Does Apisix have any memory caching mechanism? This 
problem has a serious impact。。。。
   
   Hi @start1943 ,
   
   While the problem occur,
   
   What about the CPU/Memory usage and Connection stat. Any obvious exceptions?
   How long it took before restarting APISIX?
