Error Publishing an extension in ServiceCenter

Error Publishing an extension in ServiceCenter

  
Hi all.

I'm trying publish an extension in Service Center and this return me an error "Could not assign '20' to 'Extension_Version.Xif_File'... Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.".

I can't publish that.

Any ideas, please?

Thanks.
The print error attachment.
I'd check the error log under Monitoring, and the event logs on the application server. You've got something wrong there.
