Re: [Cs-studio-users] ArchiveEngine does not reconnect channels

[Kasemir, K. <kas...@or...>]

Hi:

The does-not-reconnect issue is different from the restart issue.

So on the reconnect: Are you using the JNI JCA or the pure Java CAJ?
With JNI, and having a caRepeater running, we do not see reconnect issues
at the SNS.
With CAJ, we do see them all the time. So on the accelerator network, we
stick with JNI.

On the restart:
It could be stuck somewhere.
Pity that there's no error message that would tell us more.
If that happens again, you can use

 kill -QUIT {PID-OF-Engine's JVM}

to create a Java thread/stack dump.
It might help me to see what the engine is doing: what thread is where,
are there any deadlocks.

Thanks,
Kay
