Hi,

How did it happen?
Can you easily reproduce the issue?
Is "6.01" the version of the library? If so, any chance to use a newer version?

[kpturner]

I am afraid it is not easy to reproduce. It happens rarely (but again this morning).

We are on version 6.1.2 build 1643

I see that this version was sent to you as a temporary fix.
Since then, for Lightstreamer 5.1.x, we have released an official update 6.1.4 of the JavaScript SDK, so an upgrade is recommended.
Note that version 6.1.4 requires Lightstreamer Server 5.1.2, but if you haven't upgraded the Server yet there is no problem, as long as you don't change your javascript code to use some newly introduced API methods.

We cannot expect that the upgrade will fix the issue, but the use of an official release could simplify the investigation.
In fact, we may have to provide you with a new patched library that would help us collecting more information on the conditions in which the exception is throw.

OK I have updated the library. We will see if it happens again. As I said, it is quite a rare thing.

[kpturner]

By the way, the version number you see in the URL in the error message in the OP is our software version number - not the Lightstreamer client version number.

Version 6.1.4 build 1640.14 is now in use to catch more info

Not happened since......

Thank you for the update.
This is still the only notification of this issue we have had.

This has occurred again - but there is no more information available anywhere that I can see. Where should I be looking?
