Starting one application killed all other running programs!

This was kinda funny: I started StockMarketEye with the database on a ssh-mounted directory. After 10-15 seconds all running programs died! Thunderbird, Kate, Firefox, Yakuake...
Once when I started SME from terminal, that terminal stayed visible but dead, and displayed the message "bash-process was killed".

How could this happen?
The database is 49MB, my internet connection is not fabulous but not too bad, 10-20Mbit/s.
And even it it is too slow, how could every program get killed? X & mate still worked? --- edit: Seems X is restarted, so it is actually killed too. ---
The logs doesn't give a clue, just states "application X was killed" Yeah I know that already...

This is a Linux Mint 13 32-bit with Mate desktop.
Starting StockMarketEye with db on a local disk works fine.
(And I know how to handle it, a work-around is to simply rsync that db to local drive. I'm just curious about how this could happen.)

Check in your logs for "OOM killer terminated this process".

Nothing.

Code:

edgar ~ # grep -iR "killer terminated this process" /var/log/*
edgar ~ #

This is all I could find with OOM,
edgar ~ # grep -iR "OOM" /var/log/*

Code:
