The comment here was out of touch with the actual definition. Limiting a
log message to 9999 per minute is not much of a limit!
I suspect that I turned this way up during initial development at some
point and forgot to turn it down to a reasonable level.
static struct vlog_rate_limit dpmsg_rl = VLOG_RATE_LIMIT_INIT(600, 600);
/* Not really much point in logging many dpif errors. */
-static struct vlog_rate_limit error_rl = VLOG_RATE_LIMIT_INIT(9999, 5);
+static struct vlog_rate_limit error_rl = VLOG_RATE_LIMIT_INIT(60, 5);
static void log_operation(const struct dpif *, const char *operation,
int error);
