Recently, I used mp2 level to calculate qmmm, but nwchem could not run. And who can help me to solve this problem?

The error informations are as follows:


NWChem Property Module

util_file_name_resolve: filename too small 257

------------------------------------------------------------------------
current input line :
44: task qmmm mp2 optimize
------------------------------------------------------------------------
------------------------------------------------------------------------
There is an error in the input file
