Incorrect number of Bytes read error?

[soumyajitmandal]

Did anyone see this error? I got this at the full2 image step. I am using the baseline based averaging and wsclean branch.

Backtrace follows:

[AHorneffer]

Looks like /net/para14/data2/mandal/factor_281008/workingdir/results/facetselfcal/facet_patch_999/L281008_SBgr000-10_uv.dppp.pre-cal_chunk4_12608E368t_0g.mssort_into_Groups/table.dat is somehow corrupted. (Probably too short.)

• Is it the same size as the corresponding file in the other MSs of the same step?
• Was there some issue with the file-system? (FS full, a disk damaged or so?)

Closing for now -- reopen if this problem reoccurs.
