http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=13193 Bug ID: 13193 Summary: Discussion: strategy for diagnosing memcache issues. Change sponsored?: --- Product: Koha Version: master Hardware: All OS: All Status: NEW Severity: enhancement Priority: P5 - low Component: Architecture, internals, and plumbing Assignee: gmcharlt@gmail.com Reporter: barton@bywatersolutions.com QA Contact: testopia@bugs.koha-community.org In bug 13150, we came across the following error: Can't use string ("") as a HASH ref while "strict refs" in use at /usr/share/koha/lib/C4/Biblio.pm line 1635. Ultimately, this was determined to be caused by a corrupted data structure caused by memcache. I would suggest creating an entry in a similar hash that contains a well known string that could be checked upon entering any page. If the memcached copy didn't match the well-known value, we would know that memcache is having problems, and throw a warning of some sort, advising that memcache should be re-started. -- You are receiving this mail because: You are watching all bug changes.
