TCP: too many orphaned sockets​

一般内存满了导致

# x x pages
# pages*4k 实际内存使用
cat /proc/sys/net/ipv4/tcp_mem
cat /proc/sys/net/ipv4/tcp_max_orphans
/proc/sys/net/ipv4/tcp_max_orphans

Maximal number of TCP sockets not attached to any user file handle,
held by system. If this number is exceeded orphaned connections are
reset immediately and warning is printed. This limit exists only to
prevent simple DoS attacks, you _must_ not rely on this or lower the
limit artificially, but rather increase it (probably, after increasing
installed memory), if network conditions require more than default value,
and tune network services to linger and kill such states more aggressively.

Let me remind you again: each orphan eats up to  64K of unswappable memory.

  • DPO - Disable Page Out
    • caching hint that indicates the data referenced by the command is not likely to be accessed again and therefore is not a good candidate to keep or maintain within cache.
  • FUA - Force Unit Access
    • caching hint that indicates the data should be referenced directly from the media of the device. That is cache should be bypassed for this command.
