A normal PromoxVE Installation - so Debian.
Debian does not activate this feature per default but prepares everything
for you in /etc/default/rcS (the Vars RAMRUN for /var/run and RAMLOCK for
/var/lock).
The default size of these RAM based filesystems can be defined in
/etc/default/tmpfs via setting the TMPFS_SIZE variable.

Just wanted to let you know ... setting /var/lock back to non-volatile storage
does the trick. But maybe this should be mentioned somewhere?
