Excellent - and yes of course I was told earlier about the correct patch version to use with 5.1.2 and then just conveniently forgot about it. I think I am going senile :(

By the way, if I try to use the latest version of Lightstreamer.js with server 5.1.2 then I get constant alerts saying "License not valid for this client version".

is there something else I need...

...but not browsers that don't support TLS (like IE 6 for example). They will just fail?

That aside, are we agreed on my last statement/question:

"So, in summary, are we saying that the...

I think the answer to my last question is "no" they won't. Clients that insist on SSLv3 will not be able to establish a connection at all.

So, in summary, are we saying that the connection...

....andt he client will negotiate a connection regardless of the fact that SSLv3 is disabled?

OK I see. So I misunderstood the message. We have clients requesting SSLv3 and the server is saying that it does not support it. We currently have not <allow_protocol> settings configured at this...

Also, could you please help me explain these errors:

13:44:11 Handshake error on Lightstreamer HTTPS Server: Client requested protocol SSLv3 not enabled or not supported on 46.31.180.132:57106. ...

OK thanks for that information. The question really remains however: is there any way that I can explain the abnormally high number of connection requests? Presumably there is only one source of...

I have transferred the log file from today (with the debug information) for analysis. Thanks.

It seems there was a LPAR update applied when the issues started occurring on Saturday.

Is there any feedback on the numerous warnings and errors:

Current delay for tasks scheduled on thread pool TLS/SSL HANDSHAKE is 19 seconds.

OK I have loaded that thanks - seems OK now on that score :)

I am also looking at my own console tab in chrome while using their system and I am seeing literally hundreds and hundreds of of these failures pouring in every few seconds :(

@Mone - I am now on client version Version 6.2.5 build 1669 but I am still seeing the DOM elements building up. Eventually my browser dies as a result.

At the moment the customer has the LS...

OK thanks - I will ask what they were up to

OK thanks for the update.

I will get today's log to you as soon as I can. While it was running, the load was apparently normal on the firewall so that is both good news and bad news (from a...

While the server is offline, I observe more and more iframe elements being created in my browsers DOM. See screenshot below, Is this normal?

Update:

Some users have now been given access through the firewall.

They currently have 152 sessions and 411 connections (maximum 751). Some errors and warnings in the logs too. We will...

I have provided the logs from Saturday and Sunday to support@lightstreamer.com using https://www.wetransfer.com/#

Update: The number of connections are roughly equivalent to the number of sessions. If I take the server offline for a short period and restart it, the number of connections looks roughly double...

I will see if I can get the log from yesterday as it also occurred in a small window while i checked it.

Today the situation is thus:
All access blocked on the firewall except for our staff...

Noted about the log settings. They have the server switched off at the moment anyway because their current understanding is that with it switched on their firewall becomes rapidly overloaded.

So,...

OK thanks. My main problem (other than the cause) is that in order to get more information I need them to start the server again. The last time they started it, their firewall became saturated and...

The number of connections compared to the number of sessions is concerning me though. At a different customer where the current number of connections and the number of sessions are roughly the same.

The other thing I notice is that there are a very large number of errors being generated - all like this (coming in by the second):

Handshake error on Lightstreamer HTTPS Server:...

Keeping an eye on it now to see what is happening. The total number of sessions (bearing in mind it is 20:11 on a Sunday) keeps switching between 11 and 12 - so pretty trivial. The number of...
