Hello

Not sure this is the right place to ask but I'm rather desparate for a lead...

I'm maintaining a variety of QNAP NAS appliances with mostly good results. However recently one of them started to exhibit various problems which I managed to track to the /rev/ram0 somehow filling up after a few hours of runtime:

[/tmp] # df -h
Filesystem                Size      Used Available Use% Mounted on
/dev/ram0               139.5M    139.5M         0 100% /
tmpfs                    64.0M    512.0k     63.5M   1% /tmp
/dev/sda4               310.0M    246.1M     63.8M  79% /mnt/ext
/dev/md9                509.5M    101.2M    408.3M  20% /mnt/HDA_ROOT
/dev/md0                  5.4T      1.6T      3.8T  29% /share/MD0_DATA
tmpfs                    32.0M         0     32.0M   0% /.eaccelerator.tmp
tmpfs                     8.0M      4.0k      8.0M   0% /var/syslog_maildir
[/tmp] #

This is mostly an *nix question: how would I proceed to have a look into this ramdisk (?) to find out what's going on ? As you might have guess I am only moderately proficient in the matter.

FWIW it's a TS-459U with firmware 3.8.1 but i guess it's beyond the point for the time being.

Any pointer most welcome
