we are receiving hundreds of the following entries in our syslog. I have checked the timeouts and all seems fine. All timeouts happens at 20 seconds.
%FWSM-6-302014: Teardown TCP connection 145769459373785053 for outside:<ip add>/3873 to inside:<ip add>/135 duration 0:00:20 bytes 328 Conn-timeout
Any ideas welcome.
