Please test collapsed-fwd branch r12592 (or later): I do recall seeing the above error within the last month or so. IIRC, I fixed it. Unfortunately, I cannot recall which Squid code base had it. I hope the changes that went into collapsed-fwd r12589 or r12592 are it, but I do not really know so please update and test r12592 (or later). > This is an indication of of (pre-3.0) code that hasn't been updated to > deal with sparse objects in > memory. Squid should coredump.allowing to review the cause. I am guessing your Squid did not dump core after printing the above. IIRC, mine did not have the code to do it (a different bug). If you did get a core, please post a backtrace: http://wiki.squid-cache.org/SquidFaq/BugReporting HTH, Alex.
