Other customers who have reported this problem have also reported that setting
/proc/sys/net/ipv4/tcp_retrans_collapse = 0 has resolved this issue for them.
You can make this a permanent setting by adding the following line to
net.ipv4.tcp_retrans_collapse = 0
please let us know if setting net.ipv4.tcp_retrans_collapse=0 works for you?
If so, please close this bug. Many thanks.
when we set net.ipv4.tcp_retrans_collapse = 0, the problem is removed.
closing this issue based on comment#5.
