Hi
We have a system running yaws 1.76 on Erlang R12B-2,
RedHat Enteprise Linux, Yaws is running in embedded mode.
Where we recently had a strange error.
I do not know enough about the internal working of the SSL
application. But to me it looks
like, that for some unknown reason the ssl_server process suddenly
terminates with the
reason normal.
This causes the ssl application to be restarted, but it seems like
yaws does not notice this,
so it is still trying to use the old ssl socket <0.247.0>.
There are no other related events in the log than the ones included below.
- Does anyone have any ideas what could have happened?
- Has there been any changes in yaws since 1.76 that could help in this case,
(detecting that the ssl socket has been closed)?
(I looked in the change log but didn't see anything that seemed related)
