One reason for the OS to "randomly kill processes" is the Linux out-of- memory killer (OOM killer for short). Is there any chance that sagenb.org is running out of RAM? Are there any interesting messages if you log in and type "dmesg"? Actually, I just realized I could check this for myself, so I did... I don't see anything about the OOM killer, but there is a recurring, strange error message about "BUG: soft lockup - CPU#0 stuck for 11s! [python:8525]". I don't know what this means, or if it has anything to do with this problem.
