Lightstreamer Server all down

[EWANG]

all instances of Lightstreamer servers, running on two separated physical servers in different location, were all down at about the same time. There was no entries in the logs indicated they were shut down. And there is no system error like core dump, file system error, etc., on either Linux server. It just like there is a timer and it was trigger. All instances of LS were started at about the same time.

Any thing else we should look into?

Thanks

There are a few background activities, which may also depend on the license,
but if the failures were, in some way, related with background activities,
then something should be logged about the issue; we are available to help you inspecting the logs.

It could be useful to checkout also the console output produced by the failed processes, which may contain some system log that was not reported in the normal log files.

The Server has no shutdown hook, so, in case the JVM is closed by external action, it doesn't notify the event (or try to do it).

The interesting part is there is nothing in the console log, neither in system log.

This has never happened before. I guess we should look for some external cause, as any failure, memory exception, etc. would have been reported in the output logs.
