## Note
|
|
|
|
|
|
|
|
|
|
`babeld` can spew out massive amounts of route changes that can fill the netlink socket.
|
|
|
|
|
|
|
|
|
|
Check your values:
|
|
|
|
|
|
|
|
|
|
1. `/proc/sys/net/core/rmem_default` >= 1048576 (1MB)
|
|
|
|
|
2. `/proc/sys/net/core/rmem_max` higher than the value above
|
|
|
|
