Unknown IMS communication error

[jaz...@bc.edu]

Hi,

As of this morning, we've been having troubles auditing a particular collection (see log details below). Other collections seem to audit fine. We've tried deleting/recreating the collection in ACE and restarting tomcat, but we keep getting the same error message. Any guidance would be much appreciated.

Thanks,

Adam

Hi Adam,

Looks like this might actually be something with the IMS - it was having issues with its connection to its database based on what I see in the logs on our server. I've restarted the server and it looks to be ok now (I ran an audit myself which didn't show any ims problems), I'll have to dig in further to see if I can find out anything behind the connection issues. Thanks for letting me know about this, it's actually been going on for a few days now.

If you keep having problems auditing that collection let me know, hopefully it was just a server side problem.

-Mike

Hi Mike,

Sorry for the delayed reply. Looks like the server restart fixed everything on our end. Thanks so much for your help!
