Since clickhouse allows to execute user-specified command (i.e.
for dictionary loading), it is better not to expose them.
But there is something left for now:
- 10 -> socket:[14422712]
- 11 -> socket:[14422714]
- 12 -> anon_inode:[eventpoll]
- 13 -> anon_inode:[eventpoll]
- 14 -> anon_inode:[eventpoll]
- 15 -> socket:[14426310]
- 16 -> anon_inode:[eventpoll]
- 3 -> /proc/2739071/fd
- 6 -> socket:[14422708]
- 9 -> socket:[14422710]
And most of these (eventpoll) went from poco, for which O_CLOEXEC cannot
be passed.
