trouble with "error: event_add failed. in cpsl."

[Clay Cooper]

I'm also seeing the same errors flooding logs on my busiest server also running 1.9.1.

In your case were the error messages immediately preceeded by "error: could not event_del on close"?

after restart everything works fine but after some ours the log is

flooded wthis way:


2019-05-24 15:49:53.874400500 [1558705793] unbound[33794:3] error:

These messages continue even if no new requests arrive.


After downgrade to 1.8.1 with an unchanged configuration file the

problem went away.

I'll give 1.9.2 a try once it's available.


I replaced 1.8.1 (known to work) with 1.9.2~rc3 on one server that

"run crazy" with 1.9.1,

At least over 3 days I did not noticed the log message mentioned in

$subject - fine.


There are numerous changes between 1.8.1/utils/netevent.c,

1.9.1/utils/netevent.c

(that may introduce the failure I saw) and 1.9.2/utils/netevent.c

(that may solve the issue again)

Does this sound reasonable?
