Cmtgetlock causes freeze - Is there a way to see who is holding the lock?

My program is sitting at cmtgetlock forever and not sure why.  I stepped through all my code and don't see anythign obvious. My CMTGetLock is called after a user callback button.
Is there not a way in CVI to investigate a semaphore deadlock?

If you're using a CmtThreadLockHandle, and you're using CVI 2009 or later, you should be able to view the owning thread of a lock. For example, this is what the Variables window shows me, when I debug the ThreadLockTimeout example:

    As you mentiond "so I can see who is logging into a database that I setup"
    I believe
    Logon Trigger is one which is the solution for what you are looking for.

    Is there a way to see who made an appointment and what time/on what date they made it? Kind of like a date/time stamp for our network version of iCal? Everyone has all rights and privledges to everyone else's calendar, and sometimes we need to know who did what to whose.

  • Is there a way to see SAN luns from the UCS fabric interconnect.

                       Hello,
    I have recently added a 3rd and 4th vHBA to a B440 running RHEL5.
    Originally I had 2 vHBAs', and each created a path to 172 luns. (I was multipathed to 172 luns)
    Now I have added two additional vHBA's and my SAN admin assures me he has mapped, zoned and masked all 172 luns to the 2 new vHBA's.
    So, at this time I should have 4 paths to 172 luns....but I don't.
    What I see is 4 paths to 71 luns.
    I still see 2 paths to all 172 luns, but only see 4 paths on 71 of them.
    Its almost like my SAN admin either mapped or masked only 71 of the 172 luns to my 3rd and 4th path.
    Via the RHEL5 OS I have rescaned the FC paths, rebooted, done lsscsi, looked in the lowest level places for what devices are present on my FC channels, always I see 172 devices on the 2 original FC paths and 71 devices on the 2 new FC paths.
    My question is....is there a way to see all devices (luns) accociated with an vHBA from the command line in the Fabric Interconnect?
    My configuration is UCS w 2 FI's, using 8Gb FC connections to Cisco 9500 directors, to an EMC DMX4.
    Thanks in advance,
    Gene

    wdey,
    The link you supplied in your response is the answer.
    You can look at the devices on the FC boot paths, but not while the OS is running.
    I have a test server I could reeboot to try what you have in your document, and it does work.
    Too bad Cisco could not create a linux util rpm that would allow looking down the fabric while running. Im quit sure emulex has this kind of util, called HBAanywhere...at least for solaris.
    In any case, thanks for the link to your article, it was VERY good!
    My problem with seeing a shorter list of luns on 2 of my FC paths may get solved this afternoon by a change my SAN admin is going to make.. If it does I will post the fix.

    No, you can only see how many computers are authorised, you can't see what they are.

  • Is there a way to see who uses a database?

    I'm wondering if there is a way to do some kind of audit in SQL Server, so I can see who is logging into a database that I setup.  One client has the credentials that they need, and that's just fine.  I'm just curious to know if somewhere along
    the line the creds are leaked to another person, and then that person logs in to my SQL Server and has access to all the data.  If I could see the IP address of the machine that logs in, that would be perfect.  Anything related to that would be nice
    too.
    Thanks everybody.
    Knowledge is the only thing that I can give you, and still retain, and we are both better off for it.

  • Is there a way to see who sent airdrop pictures after they are accepted and in the camera roll?

    I am a kindergarten teacher and my students know how to airdrop pictures and vidoes to me showing their work.  The kids have thier Ipads named so I can tell who I am getting airdrops from, but once I click accept and the pic/videos go into my camera roll and  I can no longer tell who the pic/videos are from.  Is there a way to view this (I was thinking like properties maybe) so  I can give students credit for thier work?
    Or is there an easier way to accomplish this?  I can't have them send email (district policy)

    You could use an app called Three Ring, its simple and I use it with my Kindergarten class.

  • Is there a way to see who else got a mass text?

    I keep getting pictures attached to messages that were sent to me and other people. Then I get responses from people I don't know about the same message. I don't mind it and am more than willing to ignore the extra messages. I would just like to know that the original message was sent to me and other people at the same time. It seems like my phone would tell me this information when I first got it and then it quit possibly afer the last "update".
    Thanks in advance for any help you can give!

    Hi,
    There is a field on Audit Log Configuration, for Remote Syslog, with these fields:
    - Server Name    
    - Remote Syslog Audit Event Level
    I've enabled a syslog server to receive the audit logs, but the only one received are the login/logout events.
    Only on the log files obtained with RTMT I can see the update events. It would be helpful to receive these logs on a remote server to avoid the delete of the file on the CUCM.
    Any one has configured the remote syslog for audit? It requires another config somewhere in the CUCM?
    TIA

  • Is there any way to see at which frequency the Xeons are running at ?

    See topic.
    I'm looking for a small app or even a widget that shows the current CPU / core clock speed, like e.g. CoolBook for the MacBook (Pro).
    Is there anything like that for the Mac Pro ?

    Open the Terminal application in your Utilities folder and at the prompt enter or paste the following then press RETURN:
    sysctl hw.cpufrequency

  • Ping - Is there a way to see sent invites?

    I tried to send a few invites to friends to join/follow me on Ping (manually entered email addresses - ugh). However, I don't see any "sent invites" sort of tab.
    Is there any way of seeing who I invited/which invites are pending?
    Also, I sent an invite to my spam email over an hour ago to see if it was working - but the invite hasn't shown up yet. what's up with that?

    I am so sorry, I have figured this out.

    1. Try doing a hard reset:
    Press and hold both the Home button and the Sleep/wake button simultaneously for about 15 seconds and release when the Apple logo appears.
    2. If that doesn't solve the issue, backup the device and restore it as new.
    In that case, use: http://support.apple.com/kb/HT4137
    NB: set up as a NEW device because a software issue will be in the backup. If the issue persists after restoring as new, you should offer the device for service.
    If you get specific error messages/codes in iTunes when updating/restoring, check this: http://support.apple.com/kb/ts3694 for causes and solutions
    Good luck

  • Is there a way to Quickly organize, consolidate & save the Original (Pictures, Movies, etc.) yet delete all duplicate (Pictures, Movies, etc.)?

    Is there a way to Quickly organize, consolidate & save the Original (Pictures, Movies, etc.) yet delete all duplicate (Pictures, Movies, etc.)?

    I wanted to first thank you for this, as this is the only workaround literature that seems to be floating around out there.  With that said, I know it is a big ask, but is there any way that you could create a video showing step by step how to do what you do?  I have several tracks that are stuck in waiting mode, and if left in itunes, will never upload or match...they only cause the upload process to hang up and restart.  I've tried leaving it for days...I've tried converting the files, signing in and out of itunes (and itunes match), updating itunes match, and I tried your technique...unfortunately to no avail.  Perhaps I didn't do your technique correctly.  I used audacity to reverse the audio.
    ANY help would be GREATLY APPRECIATED!!!
    Thanks

  • HT1414 I just upgraded to an iPhone 5S and it is going haywire whenever I use it. Is there a way to resolve this without returning the phone?

    I just upgraded to an iPhone 5S and it is going haywire whenever I use it. It will randomly open applications, send emails suddenly before I am finished writing them, and much more. Is there a way to resolve this without returning the phone?

    Hi, jbgatch. 
    Thank you for visiting Apple Support Communities. 
    Our iOS devices use a capacitive touch screen and with it being winter in most places, a buildup of static electricity can cause the touch screen to act erratic.  Start with closing all applications open in multitasking and power cycling the device.  If using a screen protector, remove it and test without it installed.  Some cases that include a screen protector can cause this issue as well.  Try the remainder of the steps in the attached article below.  If the issue persists, a restore as new may been needed.  Make sure to backup your data prior to a restore.
