Mavericks server log flooded

Recently upgraded OS X Server 10.6.8 to Server.app 3.2.2 and now the System Log is getting flooded with the following message repeatedly...
Jan 15 15:58:34 sg-acd52 kernel[0]: *** kernel exceeded 500 log message per second limit - remaining messages this second discarded ***
Jan 15 15:58:35 sg-acd52 kernel[0]: IOSCSITargetDevice::RetrieveINQUIRYDataPage: Inquiry Failed for page 0
Jan 15 15:58:35 --- last message repeated 498 times ---
This is repeating basically every second. Only services enabled are File Sharing, NetInstall & Open Directory (and DeployStudio server). I'm trying to find the source.
Any ideas? Thanks!

What type of external storage do you have connected. The IOSCSITagetDevice would suggest iSCSI or possibly and outdated SCSI driver. Any chance you have old ATTO drivers that snuck in on the upgrade? Are you using iSCSI? Are all your volumes working? Take a look in /Library/StartupItems for legacy startup scripts. Maybe check out /Library/LaunchDaemons and LaunchAgents to see if there is any junk in there.

Mavericks Server Log Question

Does anyone know how to correct these errors in the log. I know it has to do something with LDAP but I'm not using LDAP right now. Not sure what's going on with the WebKit.Networking. I've tried to google and couldn't find much.
my server name has been replaced with "myservername"

Properly-configured and functional DNS services are critical for proper operations of distributed authentication and network encryption; for Open Directory and various other OS X Server components.
Please verify local DNS on the server. Launch Terminal.app from Applications > Utilities, and issue the following harmless diagnostic command:
sudo changeip -checkhostname
You'll have to enter an administrative password for the sudo, might get a one-time message around the use of sudo, then some configuration information will display, and then an indication that no changes are required, or that there are issues with the network or DNS configuration.

10.6.8 to Mavericks Server Upgrade loses Open Directory Users

Hi,
I have an OpenDirectory Master running OSX Server 10.6.8. An upgrade to Mavericks 10.9 has just failed.
The server has about 50 OD users and passwords need to be retained across the upgrade. Apart from OD, the only other active service is AFP file sharing.
DNS is good forward and back as per this article: OS X Server: Steps to take before upgrading or migrating the Open Directory database
I followed these Apple guidelines for server migration: OS X Server: Upgrade and migration from Lion Server or Snow Leopard Server.
I cloned the boot drive, booted from the clone, upgraded to Mavericks, then installed the Mavericks Server app.
On opening the Mavericks Server app "Configuring services' showed for 5 minutes, but then an error message appeared. I did not record it exactly, but it was something like, "There was an error configuring the server. Certificate not valid!".
I was able to continue through the error but on opening Server app there were no OD (local/network) users showing. Authentication was not happening.
I had underestimated the time to get the installation done and I had used up the window of downtime I had booked - I did not have much time to troubleshoot. So, I cut back to the original hard drive and the server is back to 10.6.8 again.
Can anyone point me in the right direction to find out what may have gone wrong? How can I get my users into 10.9 Server?
Many thanks,
b.

Linc Davis advice is spot-on, as usual.
There seem to be dozens of sub-databases in the LDAP database. A problem in any of them seems to derail the entire conversion process. I tried a straight conversion and was also disappointed that there were unresolved issues, and it meant that the conversion failed.
So I did the export route using WorkGroup Manager, and exported four sets:
Users
Groups
Computers
Computer groups
go to the appropriate pane (e.g., Users) and Select All, then choose Export, and give it a name (probably with an embedded date in case you need to do it again later)
Then use 10.9 WorkGroup Manager (available as a separate download) to Import.
When re-imported, everything worked just fine (except the passwords, which cannot be carried forward using this method). I did have to manually enable at least one service, such as File Sharing service in Server [admin], or users showed up as "not allowed" [to log in].
This entire process of getting Server 3 to work is fraught with peril, and everything converges on ONE diagnostic, "Network users can't log in". Which means you blew it, but provides no additional information about WHERE you blew it.
There do not appear to be any magic bullets. It is just a tough slog. Users who reported success after failing the first time reported they returned to fundamental principles and did all the steps over, in order, to attain success.

Messages in Mavericks Server 3.0.1 Not Working

I have set up Mavericks Server. Most things are working fine but messages, won't. When I sign into the server via the Messages app, it just says that the login is incorrect. I added the server account via System Preferences. I'm not sure what is wrong but a look in the logs shows me this:
connection to router closed Throttling respawn: Will start in 10 seconds
I'm not sure what this means or if there is any way to fix this. I have port forwarded the ports for Jabber/XMPP that are on this site.

Hello Elgringito,
thank you for your replay.
I rebooted from the Maveriks server disk (during the day we use the ML server since it works with mo problems).
I started Server 3.0.1 app
I entered Terminal and did the command you suggested: sudo serveradmin fullstatus vpn
Here is the full Terminal answer:

Mavericks Server Calendar and Contacts services won't start.

Recently the calendar and contacts services stopped working. Client computers started getting errors like this:
"The server responded with an error https://[some UID and a lot of other info]... is not a location that supports this request."
It was suggested by Apple tech support to do a free install/rebuild, but that's not really an option simply because of the wiki. I've previously spent months trying to migrate wikis from Mountain Lion Server to Mavericks server; never coming across a working solution and ending up having to copy/paste every page from the old server to the new server. Apple had no working solution for migration wikis and instead suggested a reference to a Krypted site URL (which also didn't work).
Other services are working just fine, but here are the symptoms we're experiencing:
Calendar service has reported a code 0 at one point, but did not continue the error
Calendar service has reported a code -1 at one point, but did not continue the error
Calendar service in can be toggled on, but the service never starts and stays offline even though the toggle switch is "on".
Calendar service full status in Terminal.app is stuck in starting
Calendar and Contacts services seem to take a while to load the status pane in Server.app
Client computers get repeated, non-stop, connection error dialogue boxes in Calendar.app
Occasionally when I try to see the Contacts service status by select it, I get "A networking error occurred while trying to communicate with the server" - this is using Server.app on the server itself, not from a client computer.
It seems the two primary problems are starting the services and therefore connecting to them. Other services such as wiki and filesharing are working fine.
Any ideas folks?
BTW - my Time Machine backup did nothing to help the situation.

Mavericks Server - Files/Folders disappearing when saving or copying.

Hello,
I have a Mac Mini running Mavericks(Server) with a Promise raid attached.
The users are part of a 'Staff_All' group and said group has RW access to the file server through ACL. A few times now the user has created a folder and upon copying items, saving items or even creating new items in the folder the items will disappear from their view. If I log in to the server itself the items are fully visible, and upon creating a new folder on the server and copying the folder contents into the new folder he can see the items just fine. This doesn't always happen, so the work around for now is have the user create a new folder and recopy the items into the new folder. I have tried connecting as SMB2 and AFP, same results. Nothing looks odd with the permissions.
Any insight that can be provided would be appreciated.

In the sidebar of the Server.app window, select the icon at the top with the name of the server. Then select the Storage tab in the main window pane.
Navigate to the folder in question and select it. From the popup menu at the bottom with a gear icon, select
Edit Permissions...
Verify that the permissions are what they should be, and make changes if necessary. Then, from the same menu, select
Propagate Permissions...
Check all applicable boxes, including Access Control List. If in doubt, check all boxes. Click OK.

Mavericks Server Not Disconnecting Users

I'm looking to brainstorm with others out there who have deployed Mavericks servers who are experienceing issues with file sharing services. I have about 7-8 servers that I have done recently with Mavericks Server that all experince varying levels of issues with users connecting to AFP not disconnecting properly.
One extreme case, is where a server has about 25 users, and at the end of the day, Server shows upwards of 40 connections. Many of the users will have two and three connections even though they are on one machine with one IP.
Eventually what happens is that users begin to have permissions issues, read-only notifications when trying to open a file, and the beachball when trying to save a file they were editing off the server. I have minimized the problem by having all the suers shut down their machines at night, and for some, set thier machines to never sleep during the day. I also have the server restarting every night to break the connections.
I have also gone in and turned on the disconnect idle users, changed the disconnect idle users time, and changed the sleep and idle times with no success in fixing the problem. If I don't restart the server at night, users will show connected for as long as it has been since thier initial connection. I also went into sharing in the system prefs and checked the connected users there. It is the same that shows in the server.
There are some other similar discussions out there, but I need to focus this bug on AFP.

I have played around with the idle discconect and sleep times. Here is how the AFP is set up:
afp:maxGuests = -1

Mavericks server roaming profiles

I Have been trying for days to set up roaming profiles on 3 iMacs connected to an iMac running mavericks server 3.1.1 and os 10.9.3. I've deleted the OD a few times now and I can't see why when I try to log on the password is never accepted. Very frustrating.

Hi,
When you are using the same roaming profile for a Windows client and a Terminal Services client, the profile may be inconsistent or overwritten. Configuration changes made on the local Windows desktop can overwrite changes made in the Terminal Services client
desktop or vice-versa, depending on which desktop is closed last.
For more and detail information, please refer to:

Setting up Maverick Server: hiccoughs along the way

Hi I'm trying to set up Mavericks Home Server. I'm a server novice. It is a rather time consuming and frustrating process. It is by no means something an average domestic computer user should consider, despite the apple blurb that makes it sound easy. OK enough rant (I'm clearly frustrated and have put in many unproductive hours with this)
I have bought a new mac mini, and followed Terry Walsh's guide (it was partly its availablitly that convinced me to take the plunge). I have set up a domain name, SSL certificate, and 6 network users. I have two problems. I don't know if they are related.
On a client I can log into one of the network user accounts, but then when i log out and try to log into another user, I get an error message saying the user account home folder "isn't in the usual place' - it lets me log into the account but with lots of ?? down in the dock.
I also noticed in the alerts section on the server that there was a reverse DNS problem (host name doesn't match computer name or something..? this might affect users ...). I have a dynamic IP address and an update client from dyndns which seems to work.
Any help would be much appreciated. Thanks so much

Then you've misunderstood me and extended the point about using DynDNS as a service to resolve a registered DNS name to a dynamic IP and confused it with the discussion about setting up properly an internal DNS server and DNS namespace.
"with the use of dynamic DNS as the server's own DNS and the lack of proper local reverse translations" - excuse me but where did I make such a statement? Sorry, but it seems to me you have a bit of a fixation on 'dynamic DNS'. Did you read the multiple posts where I was getting to check that his forward and reverse lookups on his local DNS were working? Where was I talking about using "dynamic DNS" for reverse lookups??
I'm going to have to disagree with your statement "but this dynamic DNS configuration does not work properly for OS X Server local DNS services." because you are being misleading and again making the assumption of mixing external with internal DNS. And again I did not make such a statement - you interpreted it as such because again, it seems to me, you have a thing about DynDNS (from your website).
You and I both know about the need for the OS X DNS server to be correct & authoritative for the domain in the network space it's sitting in - which is usually private. That domain could either be something bogus like - "mydomain.some_tld_we_hope_is_never_taken_for_the_internet" or an Internet legal domain like "example.org". If one uses an Internet legal domain like 'example.org' then as long as the OS X DNS server stays authoritative for DNS for that only inside the LAN (which it has to) there is no issue. There is no issue using the OS X DNS server in a split-horizon setup.
In the situation where one has a registered domain name (me) I use DynDNS to provide public Internet name resolution for that registered domain name. Perfectly OK and functional way to work. You need to be more clear about the distinction between public, Internet, name resolution and internal (LAN) name resolution.
"You don't have a registered domain name. You've (technically) acquired permission to use a subdomain (usually as a host name) from the organization that registered whichever dyndns domain you're using." What do you base that on? The OP has never shared his domain name so how do you know what he's got??
"If you're using dynamic DNS, you're probably also on a dynamic IP address". Sorry but I'm going to have to say that you are confusing things even further. You jump from 'dynamic DNS' (which really you need to clarify what you mean by that phrase) to dynamic IP when we are talking about DNS inside his - static - LAN address range. If you are meaning "if you're using the DynDNS service to dynamically update DNS records for your Internet domain when your site's dynamic IP address changes" well obviously that is self-evident. However in the previous paragraph you stated the OP "don't have a registered domain name". You can't have it both ways.
The OP - for his home network - is not trying to have a "dynamic DNS" for his internal network but a 'static' authoritative DNS.
Also you seem (??) to be making the assumption that the OP is going to go out and buy a fixed IP from his ISP - I doubt it.
"I'm also going to disagree with FromOZ on the use of forwarders — those add an extra hop, and — unless you're using DNS-level logging or a DNS-based network nanny filter — don't really contribute much to the whole configuration when you're running a real DNS server. With OS X Server, you really want to run DNS on your local network, too." Again you mix two concepts and confuse things.
No forwarders - well then you better tell Apple to remove the option for Forwarders from DNS settings in OS X server. They mustn't know what they are talking about.
"those add an extra hop" - please... as if the OP is going to going to notice that. Anyway the ISP is likely going to have 99.99% of the queries the OP's network wants cached on their DNS servers already, so actually it will be less hops because the OP's DNS server is not going to have to do recursion queries of the whole DNS chain to resolve addresses.
"With OS X Server, you really want to run DNS on your local network, too" ?? nowhere in the whole discussion thread have I made the statement "you must not run an (authoritative) DNS server on your local network" in fact the opposite was the case, I was helping the guy to make sure his local DNS was properly setup to serve local (authoritative).
Sorry, but I really have to say that you really added confusion to the discussion in your last post.
I think the OP is best served by purchasing a solid reference book - which is why I have been regularly pointing him to the volume which is specifically about OS X Mavericks Server.

Mavericks Server Issues

We have a server that was upgraded to Mavericks and OS X Server 3 and that's when the issues started. Folders becoming inaccessible, permission issues, file getting corrupted. We thought it was because it was an older Mac Mini, which was fine running Snow Leopard server, but the issues started after Mavericks. It was assumed part of the problem was the upgrade as opposed to a clean install. As this is a production machine, there was no time to wipe and reinstall. We also worried it was possible the hardware was going after running 24/7 for 3.5 years.
To be safe, we replaced it will a brand new Mac mini running a clean version of Mavericks server. It was fine for a few dys then the issues started creeping in. Permissions issues again, inaccessible folders, Windows shares getting kicked off and finally the log file filling up with errors (4,000+) have pushed us to the breaking point. We cannot get a full days work done on the server without having to repair something or reboot.
The error that comes up in the log and console is: Kernel: proc: table is full. It fills up the log.
DNS is not running and neither is open directory as this server is hosting a small network of users (less than 10) for file sharing of graphics files only. Some of the errors occur once a windows machine connects.
Any suggestions as to what could be causing these issues would be greatly appreciate as we are stumped. It ran fine under Snow Leopard it seems it's more Mavericks specific. The next step is to revert to Snow Leopardand pray that work.
Thanks in advance.

Long delay for login list to appear Mavericks Server

I am currently looking at an issue where the login list of users takes up to 30 seconds to appear after a user has logged out of their account. This might not sound like much time, but is a long time for the user waiting to get the list. Any ideas on where to look for a remedy, or what tests might be applied would be appreciated.
Clients are all 2012 - 2013 iMacs and Macbook Airs - About 140 nodes
Server is a new Mid 2012 Mac Pro Server running Mavericks server with all updates. Open Directory network.
Network is Gigabit with a 3com 4500 Layer 3 switch and Gig Lan switches.
Message was edited by: Don Roedl - To edit out my personal machine, which is not relevant to the issue.

Hello Don
We have experienced the same issue.
Are all clients 10.9 clients or 10.8 ?
If 10.8 home directories should be served as AFP protocol. If 10.9 clients then it is SMB ( SMB 2 ) OS X 10.10 Yosemite has moved from SMB2 to SMB3.
Make sure in clients that you have "Show fast user switching" ticked off.
Otherwise, the user logs out but the client machine will almost never unmount the previous user home directory shared point, the next user will not be able to log in.
In Server.app under File Sharing you see idle users even after successful log out. It was our case.
Some people on the internet went to the terminal to add precious terminal commands to force kill idle users after a "x" hours for instance.
http://krypted.com/mac-security/missing-server-app-settings-for-afp/
10.8 and 10.9 have differences.
I suggest you read http://www.amazon.com/Apple-Pro-Training-Essentials-Supporting-ebook/dp/B00HJUBR Q0
Even if you have lots of experience with OS X.

Clients losing bindings from mavericks server

Hi,
Yet another issue with Mavericks server. I have a Mavericks server with three replicas. This is a new install, only two weeks old. I have three hundred 10.8.5 clients bound to the directory and working fine. The issue started with a machine losing its binding, strange I thought. Maybe just a glitch, so I re- bound it with no problems. Two days later, another machine lost its binding for no reason. I rebound this too, I was starting to get that feeling in my stomach that a lot of Apple admins must get.. The next day, after functioning fine all morning, every single machine lost its binding and the directory refused to respond. All the services appear up on the server, however I cannot bind to the server or any of the replicas. It seems that when a directory master goes bust, it takes the replicas directories down too. What is the point of having replicas if a corruption can spread like this???
I have had to restore my entire hard drive from a backup. Has anyone had this problem? this operating system is in its third iteration in as many months.
HOW DOES APPLE GET AWAY WITH THIS??

More of the same for our company, too. All workstations on 10.9, I migrated from a 10.5 AFP server, which was super-stable (hence my reluctance to upgrade), to a 10.9 server. Its only function is file sharing.
It seems that if a user is disconnected for any reason-- app nap (we disabled that), machine goes to sleep, user closes the laptop to go home without closing documents and disconnecting properly from the server-- the files become ghost files and nobody is able to open them. Attempting to open them results in unresponsive applications (typically MS Office 2011 apps), and an unresponsive finder. The only solution is to restart.
I am asking users to try and remember to properly save and close documents, as well as log out of the server before they leave, but given the ability for years to just 'close and go' with 10.5 server, it's going to be a hard habit to break.
The work around is to drag the document to the desktop, rename it, and move it back to the server. The original document is shown to be in use/locked and the only way to delete is via CLI, so I have to do that each time. The document cannot even be renamed to the original document's name, or it will again show in use/locked.
Frustrating, and I'm really looking for a solution! My users are going to revolt. :/

Mavericks Server and AD File Sharing

I have been struggling with the setup of shared folders on a Mavericks Server with users connecting to it via our campus AD.
Have bound the server to the Active Directory on campus.
Created folders on a volume connected to the server for each of the individual instructors.
Activated file sharing within the server
Within Server - File Sharing - Clicked the "+" and added that folder.
Clicked the Edit permissions icon. The default is the local admin account of the Server. Changed the local account user to an AD user and give them Read/Write permissions for that folder.
Have lab machines that are bound to the AD.
Users log in via their AD credentials without a problem.
A local home managed account is created on that machine and is deleted on logout.
Have them go to the "Go" menu and connect to Server option.
Enter in the address of the server and connect with their AD username and password.
The problems are:
#1
Instructors create "DropOnly" folders within their share folder. They change the permission of "Everyone" to "Write Only"
Students connect the same way and drop folders into that "Drop Only" folder.
Instructors are not able to delete that folder after viewing it. Says they do not have the correct permissions.
Why are the folders that are put in there not taking on the permissions that allow the Instructor full control? (See screen shot of dropped in folder below)
#2
If the instructor looks at the permissions of their shared folder, Why is it that "everyone" says "no access" even though others can open it. (See Screen shot below)
Things do not seem as straight forward as they did in past server settings. While the creating of shared folders seems easier, the control of them seems less.
Any suggestions would be greatly appreciated.
Thanks in advance,
Pete

To connect up to 10 Macs for File Sharing, you do not need the complexity and restrictions of Server at all.
Create a new Account on the central machine, not an standard User or an Admin, but a Group, make the Group own the shared folder, and make everyone a member of the Group, with Read/Write access to the files.
System Preferences > Sharing > File Sharing ...
... allows you to specify how and what to Share.
