Qiqqa sometimes reports Unexpected exception (OutOfMemory) when using Sniffer with large libraries #19
Comments
…internal failures. :-(
… loading a saved session :-( ), we're augmenting the logging a tad to ease diagnosis. (jimmejardine#19)
Seems fixed as per #33. This has been an elusive bugger and a lot of time has been spent on This has also triggered me to run a Code Analysis Report on the codebase (MSVS: pick Solution > Analyze and Code Cleanup > Run Code Analysis on Solution (Alt+F11) which has led to quite a bit of code inspection and activity - see the CAxxxx commits in the tree. Considered done; any future work on this should be filed in another issue. |

Exception thrown: Insufficient memory to continue the execution of the program
Running Qiqqa in the MSVC debugger and having a quick look at the memory footprint (snapshot inspection), it turns out that in this case the LDAStuff.DocProbability and LDAStuff.TopicProbability both are huge: Count > 3.5 million, Size > 70MB each.
The next memory hog (?) seems to be a WPF component: WpfTap.WpfVisualTreeService --> Dictionary component @ Count ~ 24K and Size ~ 35MB :: I bet that's the visual list of the entire library.
However, the LDAStuff is odd to me as I haven't used Qiqqa Expedition or anything else, except the Sniffer during this session.
