Hi,
the issue happens as well if the number of threads is larger.
I just minimized the number of threads, so it is easier to see if jetty
has entered the undesirable state.
I increased the maximum number of filehandlers, but the issue still occurs.
As suggested by Simone Bordet I will create a bug ticket for this behaviour.
Thanks for your help.
Regards,
Simon Kulessa

Ok. Just thought best to rule these out sounds like the dump might
now shed light.
Just to repeat what was said prior, 10 threads rediculously low. Out
of box is normally 200, I run some servers at 600. Threads these days
rediculously cheap so no need to skimp. Retest with more.
Also, you cannot really load test with 1024 file handles. I would
suggest much more. We run at 150k handles to ensure it causes no
issues. 1024 is not appropriate for a web server. Retest with more.

To be clear, you made that curl request on the same server as
jetty and direct to it and not to any load balancer / reverse proxy.
The curl request was made from a different server.
No load balancer or reverse proxy is involved here.
Also to check that server is not out or basically out of disk space.
The are some gigabyte free so that shouldn't be an issue.
When logged in as same user as jetty runs, what is "unlimit -a"
output. This so can see number of permitted file handles,
processes etc.
ulimit -a print the following:
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 31815
max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 31815
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
These just to rule out anything environmental given the current
mystery.
