Hi everyone, This issue is resolved now. The code is not calling H5open() and relies on the default values but it is calling H5close() at the end of first pass. On the second pass the static objects are not available causing my application to fail whenever I access static objects.
I have corrected this and its working fine now.

I was going to update the group once the issue is resolved. Using the parameter less constructor for FileAccPropList resolved the issue with getCache exception. But now I am getting an exception with file creation. (This too happens on the second file in the sequence but the first file works fine). Will explore more as BM has suggested below.

However, because H5Fcreate failed, I suspect it has something to do with the status of the file or the property list. Could you check the HDF5 C Reference manual of H5Pget/set_cache to see if there is any notes that might give you some hints regarding cache/property list/brand new file? Also, how about permission to create or truncate the file? I won't be available until the evening, but I'll try to read mail before then.
