Deadlock/crash in 2.6.32.12 when copying large files

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I've hit https://bugzilla.kernel.org/show_bug.cgi?id=15578 again with
2.6.32.12 on amd64.

I can reproduce it every time when copying large (>2G) files over NFS.
The call trace is at https://bugzilla.kernel.org/attachment.cgi?id=26519

Needless to say it results in a system crash (kswapd deadlock, network stack
failure because of memory allocation failure for SKBs, etc.).

Trond Myklebust closed this bug a while ago, but apparently it's not completely
fixed and needs to be re-opened.
