Re: [Metakit] Core Dump - use of sub views ?

[Ian Fairclough]

Following are the first couple of lines that are generated by the metakit dump utility - they show the structure of the view that I am using.  The view structure is auto-generated dynamically from CORBA type-codes (I am using metakit to cache data that has it's structure defined in CORBA IDL).  Hence I am using sub-views to store data that is contained within nested sequences defined within CORBA data structures.   Thanks again if you can provide any pointers for me.   I dont know if it might be significant, but some core dumps I get are generated with stack traces indicating a problem during commit.  Is it possible that I am experiencing some kind of memory corruption that is showing itself when either trying to extend the size of a view or commiting data to a file ? (see stack trace below)   Best regards, Ian Fairclough.     data/master_DO_WO_workOrderType.dat: 1 properties
