@Alan that plugin is enabled but that config file created as empty there is no 
parameters mentioned.

@Leif Collapsed forwarding  enabled in remap config .Do you have new version of 
ATS  for red hat 6 (el6) ? If you have could you pls share ?

@susan Ok I will change the local port range .i checked while running the 
TIME_WAIT connections are more than 12000

Yes, I’d highly recommend against using this plugin. Not only is it broken in 
many ways, it’s no longer supported in new versions of ATS. And, it really 
doesn’t do you much good anyways, I’d look at the collapsed forwarding 
plugin(s) instead.

Cheers,

Looks like a problem with the "stale-while-revalidate" plugin. I know that's 
been problematic. I'm not sure what the current state is.

Yes , its generating core dump  file in traffic server root path and we are

No I did not set ephemeral ports .

Had default values already .

net.ipv4.ip_local_port_range = 32768     60999

net.ipv4.ip_local_reserved_ports =                    ###this one is empty

So its set by manually .

net.ipv4.ip_local_reserved_ports = 30000-31000

Is this ok ? .

Subject: Re: Traffic server suddenly drop the packets and crashed

Are you exhausting ephemeral ports?  What is the output of  "ss -s" on your 
Traffic Server machine? That is quite easy exhaust all of the ephemeral ports 
for a single load testing client machine between active and time-wait 
connections.

Is Traffic Server generating a core or a stack trace?  What version of Traffic 
Server?

Hi ,

We are testing 1000 client access one by one load test after  700 clients 
dropping the packets like “connection timeout” or “Connection reset by peer ” 
errors .

Ram and Cpus resources are everything is fine .Ethernet speed also 20gb/s both 
client  and traffic server  . Origin server has 2gb/s speed between ATS and 
Origin server .While running 700 requests in origin server content will be  
receiving speed less than 10Mb/s then traffic server and client getting more 
than 1Gb/s speed .

We are also monitoring that resources everything running fine but crashed the 
traffic server after 700 requests  .

Note: We are created Java player , We will give the no of  requests its call 
the particular URL based on given requests .
