Hi Giuseppe,
I think it is because you are using xquery and your backfile is huge with respect to your java memory settings. Db:create function is an updating function, so all your inserted data has to go to the pending update list (see [1] for explanation) before database creation, causing out of memory. If you want to automate database creation/update you could have a look at the xml command files, a way to create a batch of BaseX commands ([2]). In my use cases, I found it easier to write XQuery queries, which generate XML Command files, to get rid of memory concerns.
Hoping it helps,
Best regards,

Hi All,
I can create a database via the GUI, but if I use db:create [1] I get the message "out of main memory": why? Thanks!
db:create("myDB", "sourceDirectory", "destinationDirectory", map{"ftindex": true(), "language": false()} )
Best, Giuseppe
