In that case I suspect a logic in the "suspicious" code's
test. In other words it sees no changes for a long time,
then tries to check for change, thinks it sees one, and
returns a few lines, waits more and repeats.
Almost certainly a bug, report it to the module author
and/or try to debug yourself. (Putting a debug statement
in File::Tail to test when it enters that code will verify
my guess, though it won't fix it.) | [reply] |
