Robert Munteanu commented on SLING-5067:
----------------------------------------
[[email protected]] - the mock tests have recently started to fail for
me, e.g. with
{noformat}Exception in thread "oak-scheduled-executor-3"
java.lang.OutOfMemoryError: unable to create new native thread
at java.lang.Thread.start0(Native Method)
at java.lang.Thread.start(Thread.java:714)

at java.lang.Thread.run(Thread.java:745){noformat}
I don't expect to fail for someone else, my laptop intentionally has a low
process limit to catch these kinds of things :-)
git bisect indicates that this is the bad commit
{noformat}3ead30640692c1d387703e1f5c966c01f47d911b is the first bad commit

SLING-5067 sling-mock: "uniqueRoot()" to simplify creation and cleanup of
unique root paths in repository

Can you take a look and see whether there are some leaks?
I would expect that an unclosed Oak repository causes this issue, as it
internally starts some threads which are only cleaned up at shutdown. If the
repository is not shutdown then those threads will stay alive, exhausting all
available processes for my user -> OutOfMemoryError
