I guess I need to upgrade my server since it is not suitable for 24/7 operation.
After running it for months, it almost always leads to various
hardware problems.
Also, I need to become a better system admin.
A while ago, /var became full, and RDBMS servers refused to write on /var.
I spotted the cause and fixed it.
