Hello,

I am trying to insert big string into BaseX, and ended corrupting the whole database. Here a test code , can you reproduce it ?

declare updating function local:dbtest($db as xs:string) { db:replace($db,"map",<map>{fn:serialize(1 to 10000000)}</map>) };

local:dbtest("MyDataBase")

output :
