No processor available

[Hang]

Hi there,

I'm getting the following error with my Omero server:

Traceback (most recent call last):

omero.NoProcessorAvailable: exception ::omero::NoProcessorAvailable
{
serverStackTrace =
serverExceptionClass =
message = No processor available! [1 response(s)]
processorCount = 1
}

I tried to restart the server, but the error still exists.

Thanks,

Hang

Hi Hang,

can you show us the output of `bin/omero admin diagnostics` and the contents of var/log/Processor-0.log?

What command were you running? Did it previously work?

Cheers,

Hi Hang,

Thanks for the logs. Unfortunately, I don't immediately see what might be going wrong. What script is this that you are trying to run? Is it one of the standard ones?

~Josh

[Hang]

Hi Josh,

No. It's one I wrote and uploaded to omero.

[kennethgillen]

Hi Hang,

Chances are the community would want to see the script to be able to work out what's going wrong.

Can you post a github gist or similar?

Cheers,

Kenny

The problem is gone as we speak... I didn't do anything... Actually, it was the same thing when it happened last time. This no processor error seems to just pop up randomly..

Dear Hang,

That's not a problem we usually see. If you'd like to share a script that exhibits the failure then we're happy to try to check it for any clues as to problems.

Cheers,
Mark
