Benedict commented on CASSANDRA-8584:
-------------------------------------
bq. Providing a stack or filename (or both) with the error
SGTM
bq. What's the other context in which we impose no-spam, for reference?
https://github.com/apache/cassandra/blob/cassandra-2.1/src/java/org/apache/cassandra/db/commitlog/AbstractCommitLogService.java#L103
Perhaps we should have a NoSpamLogger utility class that wraps a Logger and a
minimum time interval, exposes just the basic info/warn/error\(String s,
Object... objects\) methods, and drops any messages that arrive within time
interval of the last logged message...?

> Since trySkipCache returns an errno rather than -1 and setting errno like our
> other CLibrary calls, it's thread-safe and we could print out more helpful
> information if we failed to prompt the kernel to skip the page cache. That
> system call should always succeed unless we have an invalid fd as it's free
> to ignore us.
