[erlang-questions] SASL problem

Hi Carlo!

Your script works for me, but it seems from the error report that the double
quotes around the log file path have disappeared in your case. You could try
to increase the number of backslashes - e.g. to three:

... -sasl sasl_error_logger "{file,
\\\"/home/itadm/erlang/log/prototipo_mps_sasl.log\\\"}" ...
