I didn't read the RFC, but I believe that the max value for the TTL
field is 255; either router hops, or seconds.
What kind of DB is it? Is it a MS-SQL server, Oracle, etc... As
Charles said, it is most likely an application problem, and a sniffer
will help you in tracking the problem. You can also do a debug IP
packet using an access-list that specifies the source/destination. Do
it at both the default gateway for the source and desdtination hosts.
HTH,
Brant

Jerry,
Have him show it to you. A lot of DBAs consider ping to be a
test of connectivity to a database, so it's really a layer 6/7 thing.
If the database server is busy, it may take a little while. 80 seconds
sounds kind of fishy though. ICMP uses TTL like any other IP packet, so
packets won't loop forever. Put a sniffer on there and verify what he's
telling you.

Hello group,
I had a "genius" who dabbles in his own network code
say that his Ping response time from client to his server, which is only
3 routers away, was over 80 seconds. At first I thought he meant
milliseconds but it actually turned out to be 1 minute and 20 seconds.
Question #1.) Does anyone know the timeout maximum from the ICMP spec?
I tried looking up in the RFC but was unable to find it.
Any extraneous comments welcome.
Jerry
