Hi Mark,

Image size is 1936 x 1216, data type is uint16 (~2.3MB). Camera is AlliedVision Manta G-235B, controlled with aravis+aravisGigE.
I'm saving some attributes - see the attached XML file.
I'm using Single saving mode, saving one image per acquisition at ~10 images per second.
It happens quite often, if I leave if running for couple of minutes I get the segfault.
I have not yet tried reproducing with simDetector - will do.
I'm using HDF5 ver 1.10.1 that comes with ADSupport.

The thing is that I have not noticed this problems before, this now happens on a remote machine at an experiment we are conducting. It could be the hardware..

Thank you,
Hinko

Hi Hinko,


Also, what version of HDF5 are you using, the one from ADSupport (and if so what version) or a system library version?


Mark

Subject: areaDetector and HDF5 file saving segafaults

Hi,

I'm experiencing segmentation faults that trace to HDF5 file saving plugin. This is with ADAravis camera, 10 images per second.

EPICS base is 3.15.4, AreaDetector is 3-1.
