Buffer size conflict warnings while installing on Linux

You may see buffer size conflict warnings while installing on Linux.

The following warnings may show on all distributed versions of Linux software while installing the Spectrum Technology Platform.

2019-12-06 01:37:36,317 WARN [NioChannelOptions] The configured tcp send buffer size conflicts
with the value actually being used by the socket and can lead to sub-optimal performance.
Configured 131072 bytes, actual 124928 bytes. On Linux look for kernel parameters 'net.ipv4.tcp_wmem'
and 'net.core.wmem_max'.This warning will only be shown once.

2019-12-06 01:37:36,320 WARN [NioChannelOptions] The configured tcp receive buffer size conflicts
with the value actually being used by the socket and can lead to sub-optimal performance.
Configured 131072 bytes, actual 124928 bytes. On Linux look for kernel parameters 'net.ipv4.tcp_rmem'
and 'net.core.rmem_max'.This warning will only be shown once.

These are warnings, only, and do not indicate errors. The software will still install normally after you see these warnings. To avoid seeing these warnings, you can set the following parameter values in /etc/sysctl.conf, or, for some versions of Linux, /etc/sysctl.d/:

net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_rmem = 4096 131072 16777216
net.ipv4.tcp_wmem = 4096 131072 16777216

These are example, non-required values, and these values may already be set higher on your system. Set the values net.ipv4.tcp_rmem and net.ipv4.tcp_wmem to clear these warnings.
