Collections disappearing

Hi all,
I am using eXist 1.2.6 and I am experiencing a strange issue where sometimes my newly-created collections did not get stored properly and/or disappearing. In the following example, I tried to create a collection "/db/data/patients/2910" Then, when I tried to access the collection, I saw this in log: The collection received from the cache is not the requested: /db/system/temp; received: /db/data/patients/2910 and based on the subsequent logs, it looks like eXist removed my collections; Any further attempt to access the collection gave me this message in log: - collection '/db/data/patients/2910' not found! What's more interesting is that this does not always happen; when I tried to store "/db/data/patients/2911" or "/db/data/patients/2912", the collections were stored and I could access them without problems; Not sure if this makes a difference, but I have a range index set up for the parent collection "/db/data/patients" that looks like this: /db/system/config/db/data/patients/collection.xconf: <collection xmlns="http://exist-db.org/collection-config/1.0"> <index> <fulltext default="all" attributes="true" alphanum="true"/> ... <create path="/patients/patient/@id" type="xs:integer"/> </index> </collection> Does anyone know what is happening here and how to prevent this? The log is attached below. Your help is appreciated; Regards, Adiarto -------------- Full log: 009-11-02 09:54:15,906 [http-8080-Processor24] DEBUG (NativeBroker.java [getOrCreateCollection]:605) - Creating collection '/db/data/patients/2910'... 2009-11-02 09:54:15,921 [http-8080-Processor24] DEBUG (NativeBroker.java [getOrCreateCollection]:605) -
