Hi everyone,

Thanks again for your help and hints getting this fixed for me.

I just wanted to send an update that those kernel options seemed to be the 
ticket to make it stable again.  I haven't had it hang since disabling IPSEC, 
ZERO_COPY_SOCKETS and TCP_SIGNATURE (I wasn't using md5 signatures, having any 
ipsec sessions or to my knowledge running any applications that'd be using zero 
copy sockets).
