I have recently seen a segfault when using AutoSave at much higher frame rates with the TIFF file plugin, and the same problem might well occur with the HDF5 plugin. I understand the problem, it has to do with the busy record asyn device support not correctly handling callbacks when they occur rapidly.  However, I don't think this happens with any official release of the busy module, only with changes made on the master branch. I am actively working on a fix for that problem.

You are using that fixed version.  Is it possible that one of your attributes is coming from a disconnected EPICS PV?  If so, perhaps I introduced a bug.
