Victor,

=20

The /tmp/ramdisk file is created by the sscccc daemon and is used by NGM
and the web-ui to process requests and responses between the client side
and the nfxsh side. Can you send me the results of "df" and the contents
of the files:

=20

# cd /tmp

# tar czvf  files.tgz ramdisk

=20

Also send the list of files in this directory so we can determine if it
was being used by the GUI or EMRS.=20

=20

If the ramdisk was being used by NGM or the web ui you can try
restarting the sscccc daemon to see if this clears out the contents.=20

=20

Thanks,

Charissa

I would add to this that there are no maintenance procedures associated

with the temp ramdisk.  It should not get full, as Max stated, because,

as I stated, it is only for short term temporary files.  Very short

term. It lives in memory (hence the name) and therefore is not

persistent storage, so any reboot or unmounting of that filesystem will

obviously clear it.  Do not attempt to mount or unmount it yourself.

=20

Cheers,

=20
