on the asa at sister company there is a setting vpn-idle-timeout 30

Does this mean with no activity from the other end it drops communication with that device? The vpn session itself doesnt drop just it connection with a particular server...thanks

Sounds like a typical Phase 2 SA negotiation. It's typical to see 1 unsuccessful ping while the Phase 2 SA is built.

In regards to the vpn-idle-timeout..

With DPD keepalives enabled, the tunnel will be deleted if DPD packets are exchanged for 30 minutes.

Without DPD keepalives enabled, the tunnel will be deleted if no encaps/decaps are sent/received within 30 minutes.
