My intention is create a file system in memory of size
> 128Mb and use that for my application. But, I
couldn't do that as my system hangs whenever I create
a mfs of size > 64Mb. I did the following...

a) Configured memory file system of size 128Mb using
'mdmfs' command with 'malloc' option. When I tried to
copy files to this mfs, m/c hanged after copying some
files. 
b) Then I rebooted by m/c and configured memory file
system of size 64Mb and this time the copying
operation was successful
c) I observed that the system hanged whenever I
configure a mfs of size > 64Mb and used that mfs

System details:
i386 system with 256Mb RAM running FreeBSD 5.2.1 

a) Can someone provide me hints on what could be the
problem ?
 
Thanks
