I just checked the code and do see a log entry being made at critical
level. It does not say "ERROR" like most of those things should though,
just the filename and the system error message (fixed that right now).
It may be that you missed it amongst the other informational startup
messages, or that it is in the part of "cache.log" messages that are
output before cache.log is opened - those lines currently go to stderr
and/or your system messages log (where/what that is depends on your OS).
