Hi Mark,

I'm just wildly guessing here.  Where are the files begin created?  On
/tmp?  That is, what's your current directory.

I'm not sure (from reading the man page) if you can trust that "No such
file or directory" message.  It's returning -1 and my man page just
says that "no suitable file could be created" -- well, I think we
realize that.  

Solaris uses tmpfs on some systems, IIRC, for /tmp so maybe it's an
issue with the way that file system operates -- if you are indeed trying
to create files in /tmp.  I frankly can't believe that creating three
hundred files would be a problem, though, regardless of the file system.

Swish-e uses mkstemp() to create the temporary file.  Since I'm in the
guessing phase, I'd probably write a small program that uses mkstemp()
to try and duplicate the error outside of swish.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <errno.h>

int main( void )
   int i;
   char name[1000];
   for ( i=0; i < 1000; i++ ) 
       strcpy( name, ".testXXXXXX" );
       int fd = mkstemp( name );
       if ( -1 == fd ) 
           printf("Failed on file number %d: %s\n", i, strerror(errno) );
           return 1;
   printf("Created %d files\n", i );
   return 0;

Wish I had an answer for you.  Please post back what you find.
