Hi Guys, I created a brand new directory for my dbfarm yesterday and as you can see everything was fine for 24 hours then my merovingian.log shows an error. My Compile options are: ./configure --libdir=/usr/lib64 --prefix=/usr --sysconfdir=/etc --localstatedir=/var --disable-assert \ --disable-testing --enable-optimize --enable-rintegration --enable-jsonstore http://pastebin.com/qAebcMhp I'm currently only inserting to one table. DROP TABLE "threatmonitor".http_traffic_json; CREATE TABLE "threatmonitor".http_traffic_json ( id INT GENERATED ALWAYS AS IDENTITY ( START WITH 0 INCREMENT BY 1 NO MINVALUE NO MAXVALUE CACHE 2 CYCLE ) primary key, guid char(36), recv_date date, recv_time time, json_data JSON ); Typical insert INSERT INTO http_traffic_json (recv_time,recv_date,guid,json_data) VALUES (NOW(), NOW(), '1f248d6e-ed15-2a3e-a08f-96536ed925d0', '{"http":{"host":"ad.sxp .smartclip.net","connection":"keep-alive","cachecontrol":"max-age=0","accept":"image/webp,*/*;q=0.8","useragent":"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/4 2.0.2311.90 Safari/537.36","referer":" http://cdn.turn.com/server/ddc.htm?uid=8915259122209287941&rnd=2469957418904856936&fpid=28&nu=n&t=&sp=n&purl=&ctid=3&cyid=18","acceptencoding":"gzip, defla te, sdch","acceptlanguage":"en-GB,en-US;q=0.8,en;q=0.6","cookie":"ommited"}}'); I will look more at this tomorrow and try and reproduce.
