Subject RE: Strange SSL error
Date Tue, 12 May 2015 20:28:28 GMT
I was looking at the change log for 4.4 and 4.4.1.  Count HTTPCLIENT-1609 be causing this?
 Or does it have to be something on the network closing the connection?

* [HTTPCLIENT-1609] Stale connection check in PoolingHttpClientConnectionManager has no effect.
  Internal connection pool does not correctly implement connection validation.

The scenario is that he logs in to our Swing application, there is a burst of transactions,
maybe a slight pause, and then the next one fails.  The whole process probably takes around
10 seconds.  I was actually wondering if this had something to do with bad connections in
the pool, but it is hard to say since I can't reproduce it reliably.

The communication is over SSL, and consists of readable XML and binary data.  Most of the
messages are < 10K, some bigger.  We checked the firewall wall logs (since there is a firewall
involved) and there is nothing.  I connect through the same route and this never happens to
me.

Thanks again,

What kind of data is being transfered? Do you tend to keep connections open for a long time?
Firewall killing connections?

 It is not too often, but often enough to be annoying and look like a failure in the application.

knowing where to start?   Everyone else who tries has no issues.  He logs into our application,
which involves lots of small network transactions, and then the next thing he does often causes
this.  I think the situation would be that there is a lot of transactions very quickly, then
a slight delay.  After this, the next transaction fails, and then it will be fine.  Any ideas?
