Hi All, I have a recvfile patch for samba4.1. This patch is working with linux client, But if am trying this with windows client am getting following error in my server. " Unexpected RPC Fragment size! (0)" In client side am getting "Remote procedure call failed and did not execute" And the samba share...

We are seeing the SMBD process sitting at 99.9% Are there any step-by-step troubleshooting guides to track the source of the problem? -Jeremy

Hello Experts: I understand from the samba code (3.0.25) that we use sendfile during client's Read operation. Is there a reason for not using the same for write operation? Is it to do with header processing etc. Thanks for your feedback!

Hello list, I setup Iometer to test AIO for 100% random read. If "Transfer Request Size" is more than or equal to 256 kilobytes,in the beginning the transmission is good. But 3~5 seconds later,the throughput will drop to zero. Server OS: Ubuntu Server 14.04.1 LTS Samba: Version 4.1.6-Ubuntu Dialect: SMB 2.0 AIO settings : aio read size = 1 aio write size = 1 vfs objects =

...how many threads does the smbd have active? /proc/pid/tasks will tell you. Also, can you attach to smbd with gdb and show a backtrace? Maybe it does not happen anymore under strace, but could you strace -f that smbd while its running into the issue? Ah, btw, you don't happen to have sendfile/recvfile active? I think those don't play well with aio.
