A customer reported that after applying the following changes in their machine, the problem got resolved, which goes along with point A in the KB article as to propertly tune the kernel

net.core.rmem_default = 1048576
net.core.wmem_default = 1048576
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216

exmaple sysctl -w net.core.rmem_default=N

Replace N with the desired buffer size, in bytes. To determine the value for this kernel parameter, view /proc/sys/net/core/rmem_default. Bear in mind that the value of rmem_default should be no greater than rmem_max (/proc/sys/net/core/rmem_max); if need be, increase the value of rmem_max, the same goes for the other wmem_max and wmem_default parameter.
