Hi Hinko,


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

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.
