Event Queue Deadlock Error
LabVIEW 7.1, PDA Module for Palm OS (long-time LV programmer, new to PDA module)
I am writing an app that displays a main screen of choices via Boolean button controls. An Event structure is used to detect ValueChange in the Booleans. When a button is clicked, a sub-vi is called that opens the sub-vi's front panel that has data display and a couple of buttons that are also processed by an event structure. I got a "event queue deadlocked" error message when testing. Does this application structure violate the "single event structure in a loop" rule, even though one queue is in a sub-vi? Must I use a state machine or some other architecture to make this work?
Thanks,
BevP
A lot of time has passed but now I find the same problem and I have the solution.
If you have an event structure you MUST show the control and indicators involved in the cases in the front panel and in the monitor of your PDA/Touchscreen device, because oterwise the event queue deadlocked error appears.
It makes sense becasuse if you do not show them; you will never be able to call events and the aplication is going to stuck.

Error code 501136025 Event queue deadlocked
Bonjour,
J'ai un petit soucis depuis peu, lorsque j'appuie sur un bouton via mon Touch Panel lors du déroulement de mon programme, l'erreur suivante apparait.
Error code 501136025. Event queue deadlocked
Pouvez vous me dire d'où cela peut provenir
Merci
Résolu !
Accéder à la solution.Solution trouvée!!
Je n'avais pas modifié les configuration d'apparence du VI suivant et donc il ne s'affichait pas => la structure event renvoyait une erreur car aucun évènement ne pouvait être réalisé car les bouton sn'étaient pas affichés. -
Workflow in event queue based on a deleted object
Hi all,
I'm facing a problem with a workflow that goes to the event queue, meanwhile the object is deleted and then the WF is released from the event queue in Error. The WF is based on the BO BUS2032 (sales order).
Here are the steps:
1-Sales order created or changed --> event generated --> WF linked to that event goes to event queue
2-Meanwhile the WF is the event queue waiting to be released, the sales order is deleted
3-The WF is released from the event queue but in ERROR status (this is because the BO instance does not exist anymore)
In this scenario, is there a way to end the WF with CANCELLED status instead of ERROR? is there anyy FM or exit you know ehere I can check if the BO still exists once the WF is released from the event queue?
Thanks!!!!!Some questions/options:
1) How/why does the WF go into an error exactly? Does it try to complete the first step? What if you put a condition step as a first step in the WF and check whether the object is initial and if it is, then cancel the workflow.
2) How about deleting the event from the queue from some user-exit/badi in the sales order deletion. If I remember correctly the events when queued are in table SWEQUEUE. Probably you can find some function to delete events from the queue. Take a look for example function SWE_EVENT_QUEUE_DELETE to see the idea. Or take a look into transaction SWEAD. There you can delete events from queue. Check what it does and do the same in your code.
3) Is this really a big problem? Are there so many sales orders deleted?
In general I think that the whole event queue seems to many times cause lots of problems (the event queue job disappears, WFs will not get started, and whatever.). I try to avoid using it.

Error while deleting events from the integration event queue
I am trying to delete all the events from the integration event queue after reading it, like this (this is in Java):
IntegrationEventWS_DeleteEvents_Input input = new IntegrationEventWS_DeleteEvents_Input();
input.setDateTime("");
input.setLastEventId("");
try {
((Default_Binding_IntegrationEventWS)onDemandStub).deleteEvents(input);
} catch (Exception e) {
log.error("Deleting events from integration queue failed: ", e);
}Alas, I get the following error message:
Invalid method parameter(s): 'File Id'(SBL-ODS-50007)What does this mean? What is this mysterious "File Id" it supposedly gets? I don't see it anywhere in the SOAP message I'm sending and it isn't mentioned anywhere in the docs.
Thanks in advance for any input.Dont keep this attributes null
input.setDateTime(""); //Put a Default Time way in
the past. Ex:"1/1/2000"
input.setLastEventId(""); //pass the eventIdThe documentation states that those two are optional (although they are not nillable, for some reason). I tried to set the date to today, but I got the same result. Since setting a date is supposed to delete all events older than that date, I don't think setting it in the past will delete anything. -
Error "Event Queue Overflowed​" with the "Write file to Citadel Server"
Hello,
I can import data from a file and I can see the data
in the historical database without troubling.
But I always have this error "Event Queue Overflowed", that don't perturb my data and my application (I have just this boring message).
I have tried many things :
- increasing the size of my input buffer (-> 1.000.000, no change) : I don't think so that it's important because I've tried with a value of 100 and anyway sometimes my application works with this small value of 100.
- increasing the File_location tag size (-> 260). No change.
- My write to Citadel.cfg is in the LabVIEW folder.
Can you help me ?
Thank you.Hi,
What version of LabVIEW DSC are you using? if it is 6.1, have you applied fixes linked below.
http://digital.ni.com/softlib.nsf/websearch/513AA4A0BB60D10086256B48006D44B5?opendocument
I have seen a similar issue at the link below.

Seeing " Warning The event queue appears to be stuck."
I'm seeing some strange things since I changed to v3.6.1. Could be due to other changes made at roughly the same time but I suspect it's the new jars. I was reading what Patrick wrote here:
http://blackbeanbag.net/wp/2009/07/20/coherence-3-5-service-guardian-deadlock-detection/...and I'm wondering now if my app is just not keeping up with the flow of events...?
Thanks,
Andrew

Terminating Event to Event Queue due to Work Item Lock
I have a dialog workflow task based on an asynchronous method defined with a terminating event. When the user executes the work item, the method generates the terminating event (via a V2 change document) but the work item is enqueued (locked) by the same user (locked when they execute the work item from SBWP) and therefore the terminating event goes into error and is placed in the event queue. The background job which processes the event queue does not redeliver the event so it stays in the event queue and the work item fails to complete. Other than dequeing the work item lock myself with a function call how do I get around this catch 22?
Hello Martin,
Actually, the locking happens whether I have the task as asynchronous or synchronous. The problem is the timing. If the user does not release the lock (by backing out of the dialog which is executed) prior to the terminating event attempting to enqueue and complete the work item then the event goes into error and is inserted into the event queue (and lingers there indefinitely, almost). Another issue with the asynchronous approach is that even if the user backs out of the dialog before the event actually attempts to complete the work item they will still see the work item in the inbox unless they click the refresh button when they get back to the inbox.
I have changed the task to synchronous but here is my scenario and another question.
The process being workflowed is the approval of service entrysheets (similar to an invoice if you are not familiar with External Services). In our process, there are a large number of documents being created and requiring approval by particular approvers. It is a normal scenario for an approver to have, lets say 25 documents in his inbox awaiting approval. It was not practical for him to have to navigate back and forth between his inbox and the approval task screen. Therefore, I give the users the option of (when executing a work item) having all the documents in his in-box (for this particular task) be presented in an approval list screen. They can then do a mass approval of the 25 documents with 1 click and 1 navigation. This list screen is also available to be executed outside workflow via a tcode. So, when the user executes the mass approval (either from the inbox or outside workflow) the work items are terminated via the terminating event assigned to the approval task.
A couple of issues remaining:
1) Given my example of 25 work items (user executes 1 work item from in-box
and I displayed all 25) being approved, when the user returns to the in-box, the 24
items remain in his inbox until he clicks the refresh button since these were not actually "executed" from the workflow engines point of view. However, these were terminated successfully because they were not "locked".
<b>Question:</b> Is there a way (user exit?) to trigger the inbox refresh automatically.
2) Now, the issue with the actual work item which the user executes from the inbox. As I mentioned, the work item is locked as soon as the user executes it and is not released until they back out of the dialog or logoff. So, here is what happens: If the terminating event is sent before the lock is released the event is sent to the event queue. If they then back out back to the in-box, its OK since I put some code in the SWO1 object type program (rememeber, its now synchronous) which will determine if they did the approval/rejection and the work item will complete and the event in the event queue will be deleted the next time the Event Queue Background job runs (it deletes any events for work items already in COMPLETED status). However, lets say they simply log off rather than backing up to the in-box or they don't do anything and are eventually logged off by timeout. In this case the code in the object type program to determine if the approval/rejection was done does not get executed (control does not return to the object type program) and the work item remains in "STARTED" status and remains in the users inbox and the event is in the event queue. So, now we have a work item that should be completed still sitting in the users in-box and the terminating event in the event queue. So the next time the user goes to their inbox the work item is still there. The interesting thing is that though this may be confusing to the user, if they then attempt to execute the work item, they will get a message: "Work item currently being completed by event" (Message SWF_RUN 644) and the event sitting in the event queue gets redelivered and completes the work item. To alleviate this problem I was thinking of adding a call to SAP_WAPI_WORKITEM_COMPLETE in the approval list screen after they do the approval but I'm guessing it wont work since it probably will try to enqueue the work item and it will still be locked.
Hopefully you haven't nodded off reading this rambling note...
Thank you,

Deadlock error in SSIS package
I have a SSIS package in SQL Server 2008. It has several tasks running in parallel. These jobs are Data Flow tasks and Script tasks. All these tasks are inserting/updating data on common tables. All the tasks are doing insert/update on very large data. Everything
was working fine but a few days ago the package started failing with following error.
" Transaction (Process ID 67) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim"
Kindly Suggest.Can you provide more info on the deadlock, if you turn on the
Traceflag 1222. This traceflag is responsible for printing detailed resource information for deadlocks on SQL Server. Or run SQL Server Profiler with enable event(Locks ->
Deadlock graph).
Thanks

MACOS 10.4: Solve AWT Event queue hangup
Hi,
I'm having trouble with the AWT eventqueu. On MacOS 10.4, using Java 5 Runtime, my applet sometimes blocks. When looking at the threadstack, the deadlock always appears in the Event Loop, dispatching an AWT event, blocking in the CGlobalCursorManager._updateCursor call. In fact the CGlobalCursorManager.findHeavyweightUnderCursor Native call.
I already tried some workarounds:
- overwrite the validate method of my custom AWT components. Making sure that they do not block forever. This solves the problem for events coming through the overidden component, but it has to work for every event that might trigger the GlobalCursorManager.
I had some possible solutions for which I would like some pro's and con's in this forum:
1. I could try to kill the event loop. Is it possible to quit the event loop and restart it from within the applet ?
2. Can I force each AWT container to use another implementation of the validate method ?
3. Can I set another, customized, CGlogalCursorManager ?
4. Other possibilities ?
Thanks in advance for all those responding.I think you mean that I can override the validate method for each custom UI object separately.
That's a possibility, but I was looking for a more general solution. If possible, I would to extends one
class. E.g. can I set another event queue ? That way, I could make a custom event queue in case of a Mac OS browser. -
The event queue appears to be stuck.
Hi,
I am getting the below erros

I am getting all cache events back to my client application.
is there any way to tune the event queue or something like that ?

Event ID 1058 Error Code 1326 Logon Failure; unknown user name or bad password
I am attempting to apply a group policy to a group of computers and I will get this event ID and error code generated. I can unc to the gpt.ini file. What can I do to resolve this problem? My structure is like this: I have a 2003
R2 DC located at site A (and this computer WIN7 is also located at site A) and I also have other 2003 DC's located at remote offices (across WAN links). This computer seems to be wanting to apply the GPO from one of the remote office DC's as opposed
to the local DC that is much closer - how can I change how GPO is processed on this computer?I have two Domain Controllers Main ( Main DC Win 2012) and Second DC Win 2008.
the date of some policies is not out of date....
please check these files to know the problem.

An Warning Event occurred. EventID: 0x825A0024
Time Generated: 08/21/2014 00:22:16
Event String:
The time service has not synchronized the system time for 86400 seconds because none of the time service providers provided a usable time stamp. The time service will not update the local system
time until it is able to synchronize with a time source. If the local system is configured to act as a time server for clients, it will stop advertising as a time source to clients. The time service will continue to retry and sync time with its time sources.
Check system event log for other W32time events for more details. Run 'w32tm /resync' to force an instant time synchronization.

The processing of Group Policy failed. Windows attempted to read the file \\buc.edu\sysvol\buc.edu\Policies\{31B2F340-016D-11D2-945F-00C04FB984F9}\gpt.ini from a domain controller and was not
successful. Group Policy settings may not be applied until this event is resolved. This issue may be transient and could be caused by one or more of the following:
a) Name Resolution/Network Connectivity to the current domain controller.
b) File Replication Service Latency (a file created on another domain controller has not replicated to the current domain controller).
c) The Distributed File System (DFS) client has been disabled.

Odd messages in Console log: Event queue is full!
Hi Everyone,
I have been trying to use Dolly Drive for cloud Time Machine backups, and I'm pretty certain that Dolly Drive is not the culprit, but there is some underlying problem.
I am seeing tons of these messages:
/System/Library/CoreServices/coreservicesd[29] FMOD WATCH EVENTS DROPPED!
mds[41] (Error) FMW: WE ARE DROPPING FMW EVENTS!
And these:
kernel add_fsevent: event queue is full! dropping events (num dropped events: 148; num events outstanding: 2391).
kernel add_fsevent: kfse_list head 0x832b72c0 ; numpendingrename 1704

kernel add_fsevent: watcher 0x6d2ae004: num dropped 4775 rd 3739 wr 3738 q_size 4096 flags 0x1
What is going on? What is the event queue and why is it full. I'm on a fairly recent fresh install of OS X 10.6 with the latest 10.6.7 update applied. All disk permissions repaired, Disk verified, Spotlight index rebuilt.
Help please.Yeah, I found that one. Didn't seem helpful, at least in my case.
Seems that there is some problems either with using Dropbox and having Spotlight index that directory. Whenever Dolly Drive/Time Machine starts up and calls mds for indexing, something goes screwy.
This is at least my me and a Dolly Drive tech guy figured. -
Adding another instance of Event queue in systemEventQueue
EventQueue q = Toolkit.getDefaultToolkit().getSystemEventQueue();
q.push(new EventQueue() {
protected void dispatchEvent(AWTEvent event) {
try {
super.dispatchEvent(event);
System.out.println("mty thread has started"+event.toString());
} catch (Throwable t) {
t.printStackTrace();
s_log.error("Exception occured dispatching Event " + event,
t);
});what is the use of adding an instance of the event queue to the systemEventQueue as shown in the code above.O.k. - I am not experienced in spite of many years of using this turkey. First of, the sync/don't sync button in preferences - forget it. iCal syncs with MobileMe no matter what the setting. Bummer - except that once the hundreds of duplicate, repeat events are transfered to MobileMe, you can delete them from the web interface - unlike the iCal application that forbids deleting unwanted events.
Second new discovery. You can put in a repeated event on the MobileMe website with no trouble but, bummer again, the new event on MobileMe does not sync back to the iCal on the iMac.
Final and most important discovery. I got the problem in the first place by blindly supplying the information asked for and, I kid you not, iCal 4 asks for the end date of a repeated event twice. If you answer the question twice, as I did, you get N * N events. So I hope I can avoid the problem in the future. But really, iCal needs methods to delete repeated events. Also as a former long-term Palm user, I sorely miss the option to restore a calendar from another machine. (the ability to sync or overwrite the local application). -

spid24s Error: 28005, Severity: 16, State: 2
spid24s An exception occurred while enqueueing a message in the target queue. Error: 15517, State: 1. Cannot execute as the database principal because the principal "dbo" does not exist, this type of principal cannot be impersonated,
or you do not have permission.Hi Paul,
I also had the same error on one of my servers, and it was because the user that created the database no longer worked for the company.
So when his AD account got deleted, the database had NULL as owner
Using the following query I asked for the owners of the databases:
select name, suser_sname(sid) from master.dbo.sysdatabases
So changing the owner of the databases that had a NULL owner solved the issue for me.
use <databasesname>
go
exec sp_changedbowner 'sa'
Thanks for triggering the solution.
