CAUTION: This e-mail originated outside the University of Southampton. Hi John, in addition to that we also experience apparently regular race conditions between selecting from and dropping cache tables, that may lock database access which has actually happened quite often. After killing the mysql process that runs for a long time (`mysql> show full processlist;`), all waiting requests will be processed. Kind regards Florian Am 30.05.25 um 15:39 schrieb John Salter:
I added a script to my server to log the number of search cache tables, and the min/max IDs of them for each hour. I plan to use this to redirect requests with 'old' cache ids in the query-string to a static page, which will describe (to a human) how to re-run their search, but not provide a clickable link to do so. If others are also seeing this pattern, I can share my stuff once it's ready.
