Not that I know of.

Interesting choice of mount dir names (why "ram"?) :)

Not being able to ping it is bad. Not being able to telnet to it may
depend on how much CPU resources are available
to run the telnet daemon.

What processor are you using? How big is your JFFS2 partition and what is
this program that you are running doing?

Remember that JFFS2 needs to go GC when the fs gets full (or near full if
the background GC task is running). If your program
is reading/writing from/to the JFFS2 fs it will get blocked. Are you
generating a lot of data to the JFFS2 fs?
