RE: linux-ipsec: freeswan-0.90 works, then hangs

Sean,

How much memory do you have? I had what sounds like similar problems, then discovered Linux was running on only 16MB RAM. Once this was increased to say, 64MB, the problems went away. Just a thought. I too had RedHat v5.1, Linux v2.0.35, and a similar IPsec (Aug30 snapshot).
