Re: [Samba] high cpu load
Jeremy, - Thanks for your help... We use a default user profile stored in the netlogon share. NTUSER.DAT does redirect the following folders: Registry = [Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders] Value of type REG_EXPAND_SZ, data length 74 [0x4a] H:\.windows_settings\Application Data Value of type REG_EXPAND_SZ, data length 56 [0x38] H:\.windows_settings\Desktop Value of type REG_EXPAND_SZ, data length 30 [0x1e] H:\My Documents Value of type REG_EXPAND_SZ, data length 80 [0x50] H:\.windows_settings\Start Menu\Programs Value of type REG_EXPAND_SZ, data length 54 [0x36] H:\.windows_settings\Recent Value of type REG_EXPAND_SZ, data length 62 [0x3e] H:\.windows_settings\Start Menu Value of type REG_EXPAND_SZ, data length 96 [0x60] H:\.windows_settings\Start Menu\Programs\Startup Value of type REG_EXPAND_SZ, data length 54 [0x36] H:\My Documents\My Pictures We also add a REG_DWORD value named DeleteRoamingCache to the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon \DeleteRoamingCache we also change the grouppolicy to exclude these directories in the roaming profile: Local Settings;Temporary Internet Files;History;Temp;My Documents;Desktop;Recent;Start Menu;Application Data Shouldn't the combination of these things prevent excess network traffic related to loading a roaming profile? We are using a default profile that was prepared on Win2k but all our machines are fully patched XPpro. Should we freshen up the Default User items in the netlogon folder? - Thanks, Matt Finlayson School of Engineering and Computer Science WSU Vancouver 360-546-9226 - Thanks, Matt Finlayson School of Engineering and Computer Science WSU Vancouver 360-546-9226 -Original Message- From: Jeremy Allison <[EMAIL PROTECTED]> Reply-To: Jeremy Allison <[EMAIL PROTECTED]> To: Cochran, Wayne Owen <[EMAIL PROTECTED]> Cc: samba@lists.samba.org, Jeremy Allison <[EMAIL PROTECTED]> Subject: Re: [Samba] high cpu load Date: Thu, 23 Oct 2008 16:36:55 -0700 On Thu, Oct 23, 2008 at 04:22:52PM -0700, Cochran, Wayne Owen wrote: > By client I assume you mean the user is explicitly asking for all > this data to be transferred.

Turn up the debug level on an affected smbd using smbcontrol debug 10 and then see if the client is actually requesting this data transfer. smbd doesn't stat files unless it's a client request so this may be a client issue, not a server one.

RE: [Samba] high cpu load
Interesting thought -- this seems to happen when the user logs in.
I tend to think the client machines are configured to automatically
cache all the crud in 'My Documents' onto the local machine
(which is a really lame idea). But I am still mystified why one file
would have to be stat'ed THOUSANDS of times. Anyway, I'll look
into it some more today and I'll see if there is some dopey anti-viral
software installed.

just my 2cents. What about the possibility, that an anti-vir tool scans

What is the client doing at this point ? It's very possible
that this is what the client is requesting.
By client I assume you mean the user is explicitly asking for all
this data to be transferred. This is very unlikely since this is happening
frequently throughout the day -- sometimes 5 or 6 clients simultanously --
so it must be something thats happening automatically.
Of course none of this explains why the RTF file is being stat'ed thousands
of times!

Re: [Samba] high cpu load
I think I have narrowed down the problem why smbd processes are soaking
up so much CPU on our file server. Here are some selected samples from
strace output as I attached to the offending smbd process:
Culprit #1
I took three sample snapshots, each lasted for several seconds, and I
took them
minutes apart from each other. I noticed many lines involved stat'ing
the
a single file in the 'My Documents' subdirectory:
stat64("My Documents/The Picture of Dorian Grey.rtf", {st_mode=S_IFREG|
0744, st_size=0, ...}) = 0
utimes("My Documents/The Picture of Dorian Grey.rtf", {1224548572, 0})
= 0
To see the frequency of these I grep'ed and use wc -l to get a line
count:
# grep 'stat64("My Documents/The Picture of Dorian Grey.rtf"' /tmp/
qqq.txt | wc -l
462
# grep 'stat64("My Documents/The Picture of Dorian Grey.rtf"' /tmp/

Is this intended? May be I add the printer section again and disable it. Thanks again, S.
