Re: [mat-dev] java.io.FileNotFoundException: /mat-work/nikhil/MAT1.11/ma

["Kevin Grigorenko" <kevin.grigorenko@xxxxxxxxxx>]

The error "Too
many open files" may occur because your file ulimit is too small,
system-wide limits have been exceeded, or there is a bug in MAT creating
too many file descriptors (in decreasing order of probability). Please
start a terminal and send the output of the following command:

$ ulimit -a
