Re: [equinox-dev] Administrating equinox in production

Is the OOME easily reproducible? If so, please follow up and open a bug.

Unfortunately the console is currently limited to a single connection. There are also various http consoles to look at from both knopflerfish and felix (both require some tweaking) however IMO the console is still the best bet.
It might be worth a look to see what changes are involved to support multiple telnet connections as most of the support is localized close to the FrameworkConsole class.

Hey guys,

I've doing some development with equinox and I want to bring it into production. I was quite happy with using console over telnet, but there is a problem.

I'm using framework org.eclipse.osgi_3.4.2.R34x_v20080826-1230.jar and first problem is you can connect via telnet only once. Well I couldn't connect more than once.

After doing following we got sometimes interesting problems:
echo disconnect | telnet localhost 1923

        at java.lang.Thread.run(Thread.java:735)

So my question. How can I administrate equinox via telnet or on another way so more computer can connect to. The problem is that if someone connects to telnet and stays connected nobody different can do anything on equinox.

Maybe someone have a hint or some interesting bundle.

Regards

Miguel
