Wordpress LScache Plugin: Memory spikes
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi, I have some nasty spikes on our server. They only last around 3 minutes, but we have super heavy memory usage (+95%) during that time. This leads to 503 erros. I cant seem to trace it to anything specific, but this error pops up during those. Basicly the finnish part says DB error. Do you think this could be the cause? And is there something to do about this. 021-09-27 19:01:12.343331 [NOTICE] [7907] [66.249.83.13:37034#wordpress4] [STDERR] WordPress-tietokannan virhe Duplicate entry https://www.fotomonza.com/kauppa/dji-inspire-2-xenmuse-x5s-cr... for key url kyselylle INSERT INTOwp_litespeed_urlSET url=https://www.fotomonza.com/kauppa/dji-inspire-2-xenmuse-x5s-crystalsky-kaytetty Kirjoittaja: shutdown_action_hook, do_action(shutdown), WP_Hook->do_action, WP_Hook->apply_filters, wp_ob_end_flush_all, ob_end_flush, LiteSpeed Core->send_headers_force, apply_filters(litespeed_buffer_finalize), WP_Hook->apply_filters, LiteSpeed Optimize->finalize, LiteSpeed Optimize->_optimize, LiteSpeed Optimize->_build_hash_url, LiteSpeed Optimizer->serve, LiteSpeed Data->save_url Br.
