AppleFWOHCI_Async messages in the system.log

Hello,
My system.log is filled with these messages, they repeat every second.
Jan 21 18:31:47 Maki-Mac kernel[0]: AppleFWOHCI_AsyncReceive::waitForDMA - context not going inactive.
Jan 21 18:31:47 Maki-Mac kernel[0]: AppleFWOHCI_AsyncTransmit::waitForDMA - context not going inactive.
Do these messages indicate a problem? If so what that could be problem and the solution?
Can this contribute to the sleep/wakeup problem when iMac won't wakeup after being put to sleep manually and not sleeping according to Power Saving settings?
Thanks a lot.

  • I am getting a warning need more space on my disk. I have checked the Console and there have been 4000 thousand messages in my system log in the last 2 days. I have emptied as many files as possible.

    Hi
    I am getting a warning on opening my mac saying I need more space as my setup disk is full.  I have emptied many files as well as my Trash.  I am planning to get an external drive for my photos, but it has been suggested that I check Console and under the system log the following message (of which they say 4000 messages have been logged in 2 days) '06/06/2014 16:08:23.341 com.apple.dynamic_pager: dynamic_pager: Need more space on the disk to enable swapping'.  This is a copy of one of the items.  It is from the system log.  I really do not think I have enough files to warrant this warning, with the exception of photos.  My storage shows 143 MB free out of 120.47. Thanks for any help.

    First off, no MacBook Air can run 10.3 or earlier.
    Secondly, are you sure you only have 143MB of storage free?  That's seriously low.  With MacBook Airs of 120 GB hard drives, or even 140 GB which is often the case when it says out of 120, you shouldn't allow your free space to go down below 20 GB.  MB is 1024 fold less than a GB.  So if you really have 143MB free on a MacBook Air, you are long past the minimum space you should be keeping it at, and need to start clearing a lot of space now*:

    I'm asking this thread be moved to the MacBook Air forum,a as we can't say for certain what you have when you post in the 10.3 or earlier forum.

  • Application messages are in the system log instead of the application log

    Hi SAP GURUS.
    The standard output is created from the outbound delivery .
    All the messages are hitting the system log instead of the application log .
    This is after the upgrade from 4.6c to ECC 6.0 .
    Please provide the details how to move the log to the application log since the output is the standard output (SAP provided output type ).

    There are a number of known issues with the 10g agent on Solaris and patches are available. I assume you are running the 10.2.0.5 agent since you reference patch 8477122. If this is a brand new agent installation i would start with applying the latest PSU update which contains many related fixes. If you are still getting the error after this, open an SR with Oracle Support with your specific error message.

    Hi,
    You need to check that program in debugging for the Backgournd process.
    For doing the debugging of the background process do the following steps.
    1)go sm37 and select your job.
    2)in the command line just type JDBG (not the /nJDBG OR /oJDBG) and hit enter. it goes to the debuggin mode.

  • Mdworker saturating the system.log file

    Hi,
    i have a problem on my late 2010 MBA, running 10.6.8. Frequently, the fan goes frantic, and it appears it is linked to mdworker running over and over again. It seems to be doing that when the vpn from the company is running (Juniper through Secure App Manager).
    I checked the system.log file and it is 2.63Go for the past 5 days! Mostly filled with
    Jan  3 08:45:39 Puss mdworker[59604]: socket(PF_ROUTE) failed: Operation not permitted
    Jan  3 08:45:39 Puss sandboxd[59747]: mdworker(59604) deny system-socket
    Jan  3 08:45:39 Puss sandboxd[59747]: mdworker(59604) deny network-outbound /private/var/run/mDNSResponder
    (repeated 500 times and over, and eventually:
    Jan  3 08:45:39: --- last message repeated 1 time ---
    Jan  3 08:45:39 Puss mdworker[59604]: socket(PF_ROUTE) failed: Operation not permitted

    Can the vpn really have an influence on Spotlight? What is spotlight trying to index and why is it denied?
    Eventually, i may be dreaming, but it seems that something is chewing up my SSD space. Without adding much files, it feels like free space is going down.
    Thanks for any help.

    I solved the problem by adding the hidden '/private' directory on the harddisk to the places that spotlight is forbidden to index (in the systems preference pane -> Spotlight ->Privacy)
    You have drag the '/private' folder into the locations box.
    You may have to install something like 'secrets' to show hidden folders in the finder.

    Hi,
    The Oracle database writes an audit trail of the archived redo log files received from the primary database into a trace file. This parameter specifies the level of trace that should be generated when redo logs are archived. The value of the parameter indicates the level of trace to be generated.
    Level      Description
    0      Disabled (default)
    1      Track archival of redo log file
    2      Track status of each archivelog destination
    4      Track archival operational phase
    8      Track archivelog destination activity
    16      Track detailed archivelog destination activity
    32      Track archivelog destination parameter changes
    64      Track ARCn process state activity
    128      Track FAL server related activities
    It can be used in a Primary Database or Standby Database

  • Understanding the system log (boot time 2 minutes)

    Dear Apple Discussion,
    I am trying to read the system.log correctly - mainly because my boot time is 2 minutes.
    I have read that the beginning of the boot up is indicated by the line:
    localhost kernel[0]: standard timeslicing quantum is 10000 us
    is this correct?
    Next, does the line:
    loginwindow[165]: Login Window Started Security Agent
    indicate that the login window has come up?
    If both of these are correct then my boot time should be 18s (according to the time stamps in the log) - it defefinitely is not that.
    Does the boot process start instead at this line:
    shutdown: reboot by root:
    If this were the case, the boot time would be closer to 2 minutes according to the log (which is what it actually is).
    This then brings up the next problem: the two minutes basically come from the following line:
    Nov 29 17:30:24 Purrfekt shutdown: reboot by root:
    Nov 29 17:30:24 Purrfekt SystemStarter[177]: authentication service (194) did not complete successfully
    Nov 29 17:30:24 Purrfekt kernel[0]: CiscoVPN : unloading cisco ipsec kernel module.
    Nov 29 17:30:24 Purrfekt kernel[0]: CiscoVPN : detaching from interface: en1.
    Nov 29 17:30:24 Purrfekt kernel[0]: CiscoVPN : interface en1, filter has been safely detached.
    Nov 29 17:30:24 Purrfekt kernel[0]: CiscoVPN : detaching from interface: en0.
    Nov 29 17:30:24 Purrfekt kernel[0]: CiscoVPN : interface en0, filter has been safely detached.
    Nov 29 17:32:12 localhost kernel[0]: standard timeslicing quantum is 10000 us
    ending line of the boot process occurs at (if my above assumption is correct):
    Nov 29 17:32:31 Purrfekt loginwindow[165]: Login Window Started Security Agent
    So why does it hang for so long at this one process? Am I reading the log incorrectly? I have searched around here and also on google ("slow boot time", "cisco vpn tiger", etc..) but haven't found anything relating to my problem.
    Thanks for any help.

    v.1 PowerBook G4 15''   Mac OS X (10.4.3)  

    I am trying to read the system.log correctly - mainly because my boot time is 2 minutes.
    It appears to be that a restart or shutdown process delays nearly 2 minutes rather than a startup process, presumably due to one of WindowServer children or a bug stays in Mac OS X 10.4.3 Update-- Mine delays approximately 30 - 40 minutes on PowerMac G5 2.7 Ghz on every shutdown or restart process. Your computer is PowerMac G4 so that make sense. I found a suspect application which is a security related. Although I am still investigating further because the issue does not occur on the lower drive bay where I install another Mac OS X 10.4.3 Update (but no third-party software) as a test facility.
    localhost kernel[0]: standard timeslicing quantum is 10000 us
    This is correct and the first line to display sequential events in a boot process.
    loginwindow[165]: Login Window Started Security Agent
    This is also a normal behavior.
    SystemStarter[xxx]: authentication service (xxx) did not complete successfully
    This can be displayed depending on a computer configuration.
    A sequential event from CiscoVPN: unloading cisco ipsec kernel module to CiscoVPN: interface en0, filter has been safely detached seems to be all right if you PROPERLY configure VPN policy and IPsec (Internet Protocol Security) authenticate, etc for your Cisco device. IPsec is a framework for a set of protocols for security at the network or packet processing layer of network communication.
    I suggest to check all related settings with Netwrok/Sharing panes and the router configurations for VPN (IPsec), IPv6, security, etc. Also check routing table and all socket connections after you launch Network Utility or via Terminal commands.
    FYI: interface en0 is a wired connection and interface en1 is a wireless connection such as AirPort. IPsec kernel module is a unit of kernel program or componet for IPsec.
    Hope this helps.

  • Can text messages in the incompletion log be found in any table?

    We need to store and review the text messages found in the online incompletion log.  Does anyone know if these are stored in a table?  Or if they are always redetermined upon VA01 or VA02 transactions, does anyone know at what point in what program this happens if we need to build our own custom table to capture the messages?

    The incompletion log table is VBUV - Sales Document: Incompletion Log
    I think the table is filled in one of the following:
    > Function module - RV_CHECK_DOCUMENT_INPUT
    > Include - LV45FFUV: FORM FEHLER_BESTIMMEN
    I hope this helps.
    Gerard
    P.s. Also look for structure VBUV_TAB as I think XVBUV comes for here.

    It's not really "removed". The system log is "rotated" out, at least partly to avoid having it grow too large. The older log information is in a series of files named like "system.log.0.bz2, system.log.1.bz2, etc. A file of type ".bz2" is a particular type of compressed file. Eventually the oldest of those files will be deleted. If you want to keep those forever, I'd copy off the oldest of those files on a regular basis to some other location.

  • I uninstalled Thunderbird but when i try to reinstall it I keep getting a message that the system must be rebooted to finalize the uninstall, over & over again.

    I am using a laptop with Windows 7. For several weeks Thunderbird has been running very slowly & there are messages saying a script is running too long. So I decided to try to clean up all the mail boxes, but still get the messages...so then I decided to uninstall Thunderbird and this worked correctly & I rebooted the system (as it asked me to). But when I try to re- install Thunderbird I keep getting a message that the system must be rebooted to finalize the uninstall. I did this but the same thing happens each time I try to install...so now I have no mail application on my laptop. Most frustrating but fortunately I have an iPad...
    Can someone please advise? Thanks in advance

    you original problem is almost certainly your anti virus, I would also hazard a guess your new one is as well.
    Thunderbird does not require a reboot on install, or uninstall.

  • Cube compression filling up the system logs

    Hi,
         I reloaded the inventory cube with 2LIS_03_BF (init with data transfer) with 46million records (in a single request). When I try to compress the request without the marker update BX has already been compressed with the marker update) , the system logs are getting filled up and the production system is freezing up.
        Is there any solution that makes the compression job take lesser time and generate less logs? At this time, we are not looking in to dropping the data and reloading in smaller chunks, cos that will take another 2days to reload the 46mil records.
    Thanks for any suggestions,
    Ajax.

    Hi Ajax,
    We had a similar issue early last yr. Compression uses a lot of temp spaces and fills up the logs .  You can ask your basis team to help you by increasing the MAX_LOGS parameter temporarily to complete your compression. As a last resort you can also ask them to involve secondary logs or setting the logs to "unlimited" value and rerun the compression job .However  pls note that this is limited by the filesystem size.
    Hope it helps .
