I got this working by getting rid entirely of MIT-Kerberos. It’s just not stable.
I am using the windows built-in authentication for kerberos tickets now and it seems to be stable and doesn’t crash my app pool.
My connection string looks like this now: Driver={Adaptive Server Enterprise};server=fakeservername;port=5050;Database=fakedbname;AuthenticationClient=activedirectory;[email protected];[email protected];PacketSize=4096;Max Pool Size=250;
where the fakeuserprincipal is the user my app pool uses for it’s identity and the fakeuserprincipal is the Sybase host’s ID as defined in the kerberos spn.
