Snapshot problems

Hi all,

I've been seeing a lot of exceptions/warnings in the logs for one of my applications lately, and all seem to have something to do with an unexpected snapshot state. I'm not really sure what causes this, or where to look next. Has anyone seen these before?

The first appears just to be logging from something, and not a full- blown exception:

DEBUG NSLog - decrementSnapshotCountForGlobalID: com.webobjects.eoaccess.EODatabase com.webobjects.eoaccess.EODatabase@7300c2 -- is unable to decrement snapshot count for object with global ID _EOIntegralKeyGlobalID[Media (java.lang.Integer)9755] - count is already 0 or this snapshot doesn't exist

I'm also getting a lot of these, which seem like they might be related somehow:

Error: java.lang.IllegalStateException Reason: There is no database snapshot available for the object <Disc pk:"76798"> with GlobalID _EOIntegralKeyGlobalID[Disc (java.lang.Integer)76798] EODatabaseContext.java line 4205 method objectsForSourceGlobalID package com.webobjects.eoaccess EOObjectStoreCoordinator.java line 682 method objectsForSourceGlobalID package com.webobjects.eocontrol EOEditingContext.java line 3904 method objectsForSourceGlobalID package com.webobjects.eocontrol ERXEC.java line 1036 method objectsForSourceGlobalID package er.extensions EODatabaseContext.java line 4418 method _fireArrayFault package com.webobjects.eoaccess EOAccessArrayFaultHandler.java line 70 method completeInitializationOfObject package com.webobjects.eoaccess _EOCheapCopyMutableArray.java line 38 method willRead package com.webobjects.eocontrol _EOCheapCopyMutableArray.java line 92 method count package com.webobjects.eocontrol _EOCheapCopyArray.java line 33 method _setArray package com.webobjects.eocontrol EOAccessArrayFaultHandler.java line 151 method completeInitializationOfObject package com.webobjects.eoaccess _EOCheapCopyArray.java line 126 method willRead package com.webobjects.eocontrol _EOCheapCopyArray.java line 95 method objectsNoCopy package com.webobjects.eocontrol NSArray.java line 393 method <init> package com.webobjects.foundation NSMutableArray.java line 60 method <init> package com.webobjects.foundation _NSArrayUtilities.java line 197 method arrayExcludingObjectsFromArray package com.webobjects.foundation EODatabaseContext.java line 6100 method recordChangesInEditingContext package com.webobjects.eoaccess EOObjectStoreCoordinator.java line 412 method saveChangesInEditingContext package com.webobjects.eocontrol EOEditingContext.java line 3165 method saveChanges package com.webobjects.eocontrol ERXEC.java line 947 method _saveChanges package er.extensions ERXEC.java line 870 method saveChanges package er.extensions InventoryItem.java line 427 method successfulChangeSave package InventoryItem InventoryItem.java line 799 method increaseShelfQuantityBy package InventoryItem InventoryItem.java line 499 method setShelfQuantity package InventoryItem NativeMethodAccessorImpl.java line NA method invoke0 package sun.reflect NativeMethodAccessorImpl.java line 39 method invoke package sun.reflect DelegatingMethodAccessorImpl.java line 25 method invoke package sun.reflect Method.java line 324 method invoke package java.lang.reflect KeyValueCodingProtectedAccessor.java line 65 method setMethodValue package KeyValueCodingProtectedAccessor NSKeyValueCoding.java line 1175 method setValueInObject package com.webobjects.foundation NSKeyValueCoding.java line 1205 method setValueInObject package com.webobjects.foundation EOCustomObject.java line 1601 method takeValueForKey package com.webobjects.eocontrol NSKeyValueCoding.java line 519 method takeValueForKey package com.webobjects.foundation NSValidation.java line 733 method validateTakeValueForKeyPath package com.webobjects.foundation EOCustomObject.java line 1363 method validateTakeValueForKeyPath package com.webobjects.eocontrol NSValidation.java line 551 method validateTakeValueForKeyPath package com.webobjects.foundation NSValidation.java line 741 method validateTakeValueForKeyPath package com.webobjects.foundation WOComponent.java line 1273 method validateTakeValueForKeyPath package com.webobjects.appserver ...
