Hi,
not sure if this is related, but I am also under the impression that there is
some memory issue somewhere: I am using an XPL pipe to load a document, using
XSLT to split the nodes from the root into segments of max. 500 nodes, and
then sending each of those segments to the DB. The XML file in 45MiB in size
(>9k children of the root, i.e. 19 segments), and if I give less than 1200MiB
RAM to Orbeon, it crashes with "GC overhead limit exceeded" around the 10th
segment. It feels like it's keeping much more data during that loop than it
needs.
(I previously had it send the whole file to the DB in a batch, which would
behave even worse).
This is with Orbeon 3.8 CE.
Kind regards,
Ralf Jung
