Description

Failed assert mon/Paxos.cc: 412: FAILED assert(begin->last_committed == last_committed)

I haven't spent much time looking into this, but lxo has reported seeing it intermittently. I was wondering if this could happen just by having the monitor fall behind due to slow disk syncs, but Sage doesn't think so.

oh.. maybe it was slurping, and crashed before it stashed. when it restarted it didn't go back into slurp, because the get_version()/last_committed was recent enough?

that slurp-or-no-slurp check should also verify that the stashed version is new enough?

I think that could happen, so I'll check and fix it if so, but it's not what happened here.
