APAR status

  • Closed as program error.

Error description

  • When packet transmission and adapter status query such as
netstat -v or
entstat are running at the same time, the packet to be
transmitted will
be delayed until next transmission. It may cause initial
connection
error of the application which has a short timeout value
for connect.

Local fix

  • 1. Do not run netstat -v or entstat when connect is being
called.
2. Send packets repeatedly from the adapter with shorter
interval than application timeout.

For example,

while true; do
  ping -c 1 <target address>
  sleep 1
done

Problem summary

  • When packet transmission and adapter status query such as
netstat -v or entstat are running at the same time, the packet
to be transmitted will be delayed until next transmission.

Problem conclusion

  • Driver is fixed to start send timer.

Temporary fix
