I'm getting the following in my messages log, quite frequently: Oct 10 07:46:31 kalproxy (squid): Squid has attempted to read data from memory that is not present. 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. Immediately preceeding this message is a dump of the available data in the format [start,end). The [ means from the value, the ) means up to the value. I.e. [1,5) means that there are 4 bytes of data, at offsets 1,2,3,4. Is there a patch written for this? Do I need to force squid to core in order to do the backtrace? Is the backtrace still needed?
