Application gets stuck when restarting unfinished jobs

[steviesteve]

Having a problem when running Mendix 7.5 it seems that when jobs are not finished after a restart and re-queuing is attempted the application will hang when running the start up microflow (ProcessQueue.AfterStartup_InitialiseQueue).

The area code where the app hangs is around here where the commit occurs:
javasource/processqueue/queuehandler/ObjectQueueExecutor.java:59

public ObjectQueueExecutor( IContext context, IMendixObject action, IMendixObject process, String calling_microflow_name ) 
	{
		this.context = context;
		this.QAGuid = action.getId().toLong();
		this.callingMicroflowName = calling_microflow_name;
		this.actionNr = action.getValue(this.context, QueuedAction.MemberNames.ActionNumber.toString());
		this.referenceText = action.getValue(this.context, QueuedAction.MemberNames.ReferenceText.toString());
		this.microflowName = (String) process.getValue(this.context, Process.MemberNames.MicroflowFullname.toString());
		
		this.action = action;
		this.action.setValue(this.context, QueuedAction.MemberNames.Phase.toString(), ActionStatus.Queued.toString());
		
		//Make sure we commit the latest info so status changes always get updated in the client as soon as possible.
		// E.g. actions being set to "Queued".
		if( this.action.isNew() || this.action.isChanged() ) { 
			try {
				Core.commit( this.context, this.action );
			} catch (CoreException e) {
				_logNode.error("Error while trying to commit QueuedAction " + this.action.getValue(this.context, QueuedAction.MemberNames.ActionNumber.toString()) + " from queue", e);		
			}
		}
	}

Commenting the commit out out seems to resolve the problem

Any thoughts on this would be appreciated
Cheers
