My design is crashing in route:
    `Layer 1 overflow: 0`
    `Layer 2 overflow: 0`
    `Layer 3 overflow: 0`
    `Layer 4 overflow: 0`
    `Layer 5 overflow: 0`
    `Layer 6 overflow: 0`

`[Overflow Report] Total Usage   : 4308733`

`[Overflow Report] Max H Overflow: 0`
`[Overflow Report] Max V Overflow: 0`
`[Overflow Report] Max Overflow  : 0`
`[Overflow Report] H   Overflow  : 0`
`[Overflow Report] V   Overflow  : 0`
`[Overflow Report] Final Overflow: 0`

Any ideas what could be the problem... maybe Total Wirelengh shouldn't be negative?

git clone <https://github.com/efabless/openlane.git> --branch develop
cd openlane
git checkout 40e97e34a34d11727d037401956c3c1e4792cc86

Do I also need to update PDK? I now get

I wouldn't suggest checking out to a random commit of develop. Either use master, or latest develop but always assume that develop might not be stable.
<@U017FJJJ8P2>: how big is your design? Does it have any macros inside it?

Change the way you're starting the docker container

The box has 24GB of RAM. Is it a docker limit?

Yeah, there's a RAM limit in the container start configuration
