Racoon error?

[jzsjr]

Any ideas on this:

Apr 18 11:40:03 racoon: ERROR: Cannot record event: event queue overflow
Apr 18 11:40:03 racoon: [SonicWall]: INFO: ISAKMP-SA deleted 24.30.9.196[500]-216.235.148.194[500] spi:84b2cc71a13445bd:dad3b3a410c44ef2
Apr 18 11:40:02 racoon: INFO: DPD: remote (ISAKMP-SA spi=84b2cc71a13445bd:dad3b3a410c44ef2) seems to be dead.

I'm trying to figure out why the remote seems to be dead or why the connection is not being reconnected.
thanks,
Jim
