Hi,
I tried some of the network tuning suggestions made by other people on this
list who faced similar problems:
net.core.rmem_max = 33554432
net.core.wmem_max = 33554432
net.core.rmem_default = 87380
net.core.wmem_default = 65536
net.core.optmem_max = 25165824
net.ipv4.tcp_rmem = 4096 87380 335
I was get same situation at 1gbit network. Try to change mtu 9000 on nic and
switch.
Do you show cluster configs?
