Good news then!

Hmm, according to ovdb documentation:
https://www.eyrie.org/~eagle/software/inn/docs/ovdb.html
readserver
When the readserver parameter is true, the nnrpds will access overview
via a helper server (ovdb_server -- which is started by ovdb_init).
This can also result in cleaner shutdowns for the database, improving
stability and avoiding deadlocks and corrupted databases. If you are
experiencing any instability in ovdb, try setting this parameter to
true. Default is false.
A nice way to say that bugs exist :)
I would suggest to set the default value of this parameter to true in
the samples and documentation of the upcoming INN 2.6.2 release, and
mention the above issues as a cave-at if this parameter is changed to false.
I believe it will prevent people from having a bad experience like you
had with ovdb.
Any objection to that change? (Incidentally, do you think other default
parameters should be adjusted?)
