We're using Libreswan 3.25 (netkey) on Linux 4.15.0-1020-aws and are seeing
the following error pop up in our pluto logs from time to time, sometimes
several per hour.
ERROR: recvfrom() failed in netlink_get. Errno 105: No buffer space
Our CPU usage has stayed below 40%, and memory usage has stayed below 50%.
Is there some value we can tune with sysctl that will affect the buffer
associated with these netlink sockets?
What else should we be considering?
Thanks for any guidance you can provide.
