Hi.

Thanks for the information. We use FreeBSD-based PF firewalls and all the 
timeout values are on default in there and none of them is less than 15s:

tcp.first 120s
tcp.opening 30s
tcp.established 86400s
tcp.closing 900s
tcp.finwait 45s
tcp.closed 90s
tcp.tsdiff 30s

Any more guesses? May it be some hardware-related stuff?
