Dear all,
I'm using trafficserver 4.2.3 with cluster 3 node, recently, the cluster is not
stable at peak time, at that time, http request rate to each node is about 4k
req/s , the load of server (CPU, RAM, Disk) is not the problem, could any one
help me about this issue?
The diags.log show up the message below:
[Jul 19 21:32:12.776] Server {0x2b2bc8706700} NOTE: Network congestion to
[10.10.10.7] encountered, reverting to proxy only mode[Jul 19 21:32:13.729]
