|Product Version||YaCy 1.9|
|Target Version||Fixed in Version|
|Summary||0000769: http interface is not responding after crawling for a while.|
|Description||I set my peer to crawl at approx 10% of peak speed overnight (500 PPM).|
Log files indicate it is still working.
I downloaded Visualvm and ran that and not sure of the command to get a heapdump?
Did a few screen dumps a threaddump and 2 yacy logfiles.
Also have a host file.

I have noticed on a forceful end task (pkill) when starting again it opens crawler stacks with 0 urls.
Also Pi config -XX:+UseParNewGC -XX:ParallelGCThreads=2
Old pc -XX:+UseParNewGC -XX:ParallelGCThreads=8 -d64

Cloned and did a fresh peer after running e4defrag and started to crawl a few sites it was still crawling this morning. 500 ppm was the top crawl speed.
Using -XX:+UseParNewGC -XX:ParallelGCThreads=7 -d64
Why does the fresh install Version show up 1.921/9000?
All the others upgrades where 9388.
Did a heapdump and found the file.

I will try the other peer after upgrade today sometime.

I enabled the jsresort and it crashed my peer.
I did an emergency restore of /DATA/index/*.* to another newfolder of a yacy server because of disk performance issues in the particular folder I was using.
I tested with dd if=/dev/zero of=/mnt/md0/test bs=512k count=20
and had over 600 MB/s an hot upgrade with yacy stopped I was getting lessthan 1 MB/s transfer.
I modified Grub. EDIT: to solve this, either remove enough RAM, or add “mem=8G” as kernel boot parameter (e.g. in /etc/default/grub on Ubuntu — don’t forget to run update-grub !) https://fhackts.wordpress.com/2014/03/10/very-slow-disk-write-performance-linux/ [^] I have no idea really but there is a hs_err_pid24830.log in the old yacy folder. #ShiftDel
I am running a trial Polipo Proxy DNS cache server to see if that helps.
I ran DNS Benchmark for https://www.grc.com/dns/benchmark.htm [^] with Playonlinux and rebuilt the custom resolvers list this may help.
busy:collecting 8087 documents from the collection for harvestkey null, partitioned by responsetime_i
Something about long string.
I removed some html files later on.
Hi smokingwheels, quite much data to analyze here :)
In the log files you provide in yacylogs30am.tar.gz, apart the traced OutOfMemory error, there is an interesting recurrent exception :
There is maybe something to dig here. And this kind of error seems to be mentioned in some other projects using Jetty as a webserver...

Dont worry to much I think my file system was set too high (775).
My Limit Crawler sits at 0 now.
Fixed now but thats the sort of thing that can happen if you leave the door open now days.
If you could run the jetty server thread in a controlled background process that may help. Sort of like a silent 503 but keep the caller online.
hooray! it's snowing! it's time to make a snowman.james runs out. he makes a large pile of snow. he places a huge snowball on top. he adds a headband and a hat. he adds an orange for the nostril. he adds coal for the eyes and buttons.within the night, james opens the door. what does he see? the snowman is transferring! james invitations him in. the snowman has by no means been interior a house. he says hey to the cat. he performs with paper towels.a moment later, the snowman takes james's hand and goes out.they move up, up, up into the air! they may be flying! what a terrific night time!the following morning, james jumps off the bed. he runs to the door.he desires to thank the snowman. however he is long past.
