Hi Dimos, What version of HDF5 are you using? Are you using H5Pset_libver_bounds() to set a particular version of the file format (e.g.: H5F_LIBVER_LATEST)?
Can you reduce this to a small C program that demonstrates the problem? Thanks, Dana Robinson Software Engineer The HDF Group From: Hdf-forum [mailto:[email protected]] On Behalf Of Dimos Stamatakis Sent: Wednesday, November 2, 2016 6:29 AM To: [email protected] Subject: [Hdf-forum] strange error on Fclose() Hi everyone, I experience a strange error on Fclose(). My application simply opens a file, then opens some existing groups, creates a number of groups, and finally closes all groups and the H5 file. When I create a large number of groups (above 1000) I get this error: H5Fsuper.c:1068: H5F_super_dirty: Assertion `f->shared->sblock' failed. Seems like the f->shared->sblock does not have a right value. Do you have any idea of what could cause this error? Many thanks, Dimos
