How large is your database ?
log in via SSH (puTTY) into your MB Pro and check (user + password are the same as for the Web UI)
enter
# df -h
you should see something like below
root@MeteoBridge:~# df -h
Filesystem Size Used Available Use% Mounted on
rootfs 9.1M 3.3M 5.8M 36% /
/dev/root 5.5M 5.5M 0 100% /rom
tmpfs 25.0M 15.2M 9.8M 61% /tmp
/dev/mtdblock5 9.1M 3.3M 5.8M 36% /overlay
overlayfs:/overlay 9.1M 3.3M 5.8M 36% /
tmpfs 512.0K 4.0K 508.0K 1% /dev
/dev/sdb 927.9M 808.9M 55.0M 94% /tmp/mnt
what's the size of your /dev/sdb ? how much used, how much available.
That's your internal flash memory storage of the MB Pro where the database resides
then
# cd /tmp/mnt
# ls -l
root@MeteoBridge:/tmp/mnt# ls -l
-rwxr--r-- 1 root root 257 Oct 4 2020 0-don't touch dbase and dbase.ram nor data dir.txt

here you see what all uses the internal storage (mounted into /tmp/mnt)
there should be a few files starting with dbase
what's their size altogether ?
the whole number you should get by du -sh in the /tmp/mnt directory:
root@MeteoBridge:/tmp/mnt# du -sh
807.8M .
in the example case there are only 55 MB free - not very much.
You could try using an external and bigger e.g. 4/8/16 GB USB stick for the database.
- In the administration tab at Database Media choose USB stick on front panel (can also be back panel)
- copy your last database backup on the USB stick and rename it from dbase-202108012021 (example) to just dbase
(if you don't have a backup
, copy the existing database from /tmp/mnt onto the USB stick)
- plug in the USB stick into the port you have selected under Database Media
- reboot
MB should now use the database on the USB stick
the "old" database will remain in /mnt/tmp
check the logging if you still have an out-of-memory issue.
If that solves your issue and you need to continue using the external USB stick for a longer time, it's advisable to exchange the standard USB by a stick with industrial flash memory in order not to die early due to too many I/Os
), nothing changes in the system information view, I'd say the device is defective.
