BROKEN plugin-autoclean: Plugin marked as important, shutting down lightningd!

[marimes]

Issue and Steps to Reproduce

• never ran autoclean in the past
• lightning.sqlite3 is 6.7 GB
• node has routed 230k transactions

I am getting the following error when running autoclean-once with subcommands succeedforwards, failedforwards, or failedpays:

marius@mlbb2:~$ lightning-cli autoclean-once succeededforwards 86400
{
   "code": -4,
   "message": "Plugin terminated before replying to RPC call."
}

I can autoclean expiredinvoices without an issue:

lightning@mlbb2:~$ lc autoclean-once expiredinvoices 86400
{
   "autoclean": {
      "expiredinvoices": {
         "cleaned": 0,
         "uncleaned": 1745
      }
   }
}

When I run have cln run autoclean (instead of running autoclean-once manually) then it will take lightningd down with the following log entries:
