use MWORDS=50 and MEMDDI= 200 (some maximum value as per the molecule size) in $CONTROL input, and if this doesn't work try to increase both MWORDS and MEMDDI values

Instead of using MWORDS, you can just use the MEM keyword, which accepts the size of memory available for Gaussian both in words and bytes (the latter is easier to use). You shoud add the line before the main Gaussian command line and starting with "%", e.g.:

%Mem=1Gb

The standard unit in G03 and G09 is byte, but Gaussian recognizes also KB, MB, GB, and TB.  Read more here: http://www.gaussian.com/g_tech/g_ur/m_running.htm (controlling memory usage).

Obviously you can't realy request more memory that is available physically on your machine. Bear in mind, that some Gaussian jobs (particularly MP2 and higher order perturbation calcualtions, frequency jobs and jobs with huge basis sets) may have very large memory demands, much higher than your machine's RAM. 

OK thank for yours' cooperation I'll check on these .

increasing the MWORDS capacity up to 200 makes the compilation done ,thank in advance
