During a long upload of webpages, each memcache gets filled near equally fast so that the global memcache limit is usually triggered before the max memcache size. Since that emergency flush does not trigger compactions, the number of store files just keeps growing until it fails on all kinds of errors. We need a better story for this as this is a "normal" situation. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
