"backend-exception" error

Wed, 04/29/2009 - 21:00 — ninjastyle

Occasionally when I attempt to search PubMed/MEDLINE databases, I obtain a "backend-exception" error.

For example, when I type in a search for "SSRI Horberg", I obtain the following error message:

backend-exception Exception from Backend: bePfetch (%23PmXmlSrv): Error+111+(Connection+refused)

If I hit "go" another time, two more times, eventually I get the search result I am looking for. Curious though, what is the cause of this error? Thanks.
