It seems you're using a 1 minute polling interval. Have you tried with a 5 minute one ?

the ghost threads are increasing as well.....

Post your technical support page. What is your OS and version "uname -a".

Also, when these threads get stuck, perform a truss on one of them and post the output.

Do a "man truss" and you will get your instructions.

Thanks,

Hi,

I have took a look when this happens. Everytime when I get these error messages in the cacti log:

02/20/2008 07:00:26 AM - SPINE: Poller[0] ERROR: A database insert failed! Error:'1062', SQL Fragment:'INSERT INTO poller_output (local_data_id, rrd_name, time, output) VALUES (1581,'hdd_used','2008-02-20 07:00:24','22072528896'),(1581,'hdd_total','2008-02-20 07:00:24','48417910784'),(1582,'hdd_total','2008-02-20 07:00:24','2593718272'),(1582,'hdd_used','2008-02-20 07:00:24','408158208'),(1586,'traffic_in','2008-02-20 07:00:24','1150309732'),(1586,'traffic_out','2008-02-20 07:00:24','516726394')'

then the spine processes are dying and resides as zombies. After some days these zombies has allocated all of the memory of my cacti machine.....

Any ideas?

Hi,

I found out what the problem is: when I leave the threads parameter at "1" all is running fine - at the point I increase threads to 2 and more I get massive error messages and many zombie threads.....

Only for your interest if anyone has got the same problems....

Alex,

Please use the SVN version, and let me know if the problem goes away. There have been a few critical changes.

However, threading issues in spine for Linux have not been seen for quite some time.

I tried bumping the mysql max conns up to 1000 but with no change. Spine 0.8.7a currently.
