(1) Install the haveged daemon to ensure sufficient entropy
or
(2) use -Djava.security.egd=file:/dev/./urandom so that Java uses less strong randomness.

Now it took about 5 minutes after reboot to start up the handle server down from 15 minutes. Here is the dump.

If startup is slow again, please try to get the thread dump to send to
us.
Thanks,

Oh, I see that the process was just slow to start up.
Do you have a very large number of handles?

Does the process stop, or does it hang? If it hangs, please find
the
process-id (using "ps auxww | grep java" for instance) and get a
thread dump (using "kill -QUIT process-id").
Thanks,

Yes. I have deleted everything in /bin and /lib folder and then
copy things over.
Right now when I run /hs/bin/hdl-server /hs/svr_1 It will show
this

It will stop there. I can't find any error log. The "delete_me_to
_stop_server" file didn't get generated. I can't get to port 8000

You should make sure you entirely replace the bin and lib folders,
and not just copy the new content over the existing content.
What makes you think your "server doesn't seem to work right"?
What did you try, what did you expect to happen, and what actually
happened instead?

A new version of the Handle.Net software, v9.1.0, is now available
for download at https://handle.net/download_hnr.html .
Version 9.1.0 allows for significantly higher throughput for admin
operations, due to improvements in the code for storing
transactions for replication to mirrors. See the Release Notes at
https://handle.net/HN_v9.1.0_ReleaseNotes.pdf .
