Out of socket memory error #22

Open amarmudrankit opened 9 years ago

Hi,

I received the following kernel error while running the fatcache:

 kernel: Out of socket memory

Setup:

96 GB RAM
1 TB SSD
8 fatcache instances each with ~21GB of memory each -m 21760 -i 64 (12 core box)
Running a "memslap" client creating thousands of connections (~36 K connections) to fatcache
When the free memory left is around 5 GB, I see the above error and memslap stops
2.6.32 kernel

Let me know if you need any other information

hi @amarmudrankit: Fatcache may cause too many orphan sockets, as fatcache didn't close client fd. It was fixed at this pull request (https://github.com/twitter/fatcache/pull/19). Whether you code is the latest version？
