How are you? I have similar topology at work and issue we see is remote end db servers SQL db servers makes call to collect logs from home office SQL db server and sometimes it droops. End to end host connectivity is there as well as IPSEC is all up, VPN is up too. Even I see net flow via LIVE action network analyzer tool.
From home office ASA 5505, I have loggedout /in site to site vpn session which reestablishes with in 30 se . ASDM packet tracer would isolate issue ? I am not sure if that could be something high on CPU or memory to spike ?
Would Clear connection and clear xlate would help?
is it service affecting event?
Is there any other test or troubleshooting would you suggest on intermittent drop like this?
