------------------------------
Summary: usually harmless "Broken pipe" errors filling up
dspace.log
Key: DS-1448
URL: https://jira.duraspace.org/browse/DS-1448
Project: DSpace
Issue Type: Bug
Components: XMLUI
Affects Versions: 3.0, 1.8.2
Reporter: Ivan Masár
Priority: Trivial
This error occurs every time the TCP connection is interrupted before the page
is completely served. Although sometimes it might indicate a problem, in 99% of
cases it just means that the user interrupted loading the page in their
browser. Therefore it doesn't deserve a full stacktrace in the log. I suggest
we catch it and display only a one-line warning.
