Image Integration crash

[dougj7]

The latest version with all updates still crashes during "integrating channel 1 of 3". The only option changed to the image integration process was under pixel rejection I selected  "winsorised sigma clipping". 22 .fits images from my qhy8l ccd. Using the Win32 latest version of Pixinsight with all updates installed. I reverted back to version 01.07.00.0697 and was able to successfully perform imageintegration with the same files. Not sure if this is enough information for this bug, please let me know. -Doug

Hi,

What do you mean by "crashes"? What error message are you getting?

If it is an out of memory error, then you can try lowering the "Buffer Size" parameter to 8 MB or less. Your best option is of course a 64-bit version of PixInsight running on a 64-bit operating system.

Microsoft Visual C++ Runtime error. If memory was an issue, wouldn't the previous release of pixinsight have posted the same error? My hardware hasn't changed. Windows 7 32bit, 4gig ram.

If memory was an issue, wouldn't the previous release of pixinsight have posted the same error?

Memory requirements tend to increase with each new version, in general.

This problem seems the same as this one:

Try decreasing the stack size parameter in ImageIntegration and perhaps also buffer size. As a proof of concept, try setting stack size to 100 MB instead of its default value of 1024 MB. Also try seting buffer size to 4 MB instead of 16 MB.

Thank you Juan,

reducing the buffer and stack size worked. no more crashes.
