This is definitely not right.

Not sure what the default value for AES is (for BF-CBC it's 60 minutes),
but it should be in the "many hours" range.

Check your config for "reneg-bytes", "reneg-pkts" and "reneg-sec" settings
that are non-default.

(If this is not fruitful, try re-running with "verb 4" and see if there
is more insight)
