   When it fails (seems intermittent but with high frequency) it fails consistently with the same exception: “Mempool sync failed”.

   However where exactly it happens seems random, though it’s always triggered by a sync_all().

   • in https://travis-ci.org/bitcoin/bitcoin/jobs/184431201#L3798 it’s the sync_all on line 534 that fails
   • in https://travis-ci.org/bitcoin/bitcoin/jobs/184473580#L2953 it’s the one on line 461
   • in https://travis-ci.org/bitcoin/bitcoin/jobs/184333528#L2919 it’s the one on line 449
   • in https://travis-ci.org/bitcoin/bitcoin/jobs/184328060#L3450 it also happens on line 534

   I cannot reproduce this locally.

   This has likely been triggered by one of yesterday’s merges:

   • Merge #9322: [qa] Don’t set unknown rpcserialversion
   • Merge #9313: If we don’t allow free txs, always send a fee filter
   • Merge #9331: [qa] Add test for rescan feature of wallet key import RPCs
   • Merge #7562: Bump transaction version default to 2
   • Merge #9172: Resurrect pstratem’s “Simple fuzzing framework”
