cactid hangning when run from cron [SOLVED]

[Devil]

I was forced to run cactid because i poll a little over a 100 hosts (and more i getting added when i can get cactid to work). and when i run poller from cron the cactid process hangs and returns a max execution time of 296 seconds exceeded.

When i run cactid from the prompt it works like a charm, it polls all the hosts and updates the rrd-files.

the system im running is a Debian Linux with php-4.3.10, mysql-4.1.10, cacti 0.8.6c and cactid 0.8.6d. I have reinstalled all the mentioned programs, not using debians packets.

Back off to Cactid 0.8.6b and let me know if the problem persists.

I have now tried with cactid versions:

• 0.8.6a i get segmentation fault
• 0.8.6b i get segmentation fault
• 0.8.6c if i run cactid directly it runs perfectly, if i run from poller.php it times out.
• 0.8.6d if i run cactid directly it runs perfectly, if i run from poller.php it times out.
• 0.8.6e i run cactid directly it runs perfectly, i run from poller.php it times out.

Devil,

Please check your table poller_output and clear it if it has lot's of rows. From mysql:

truncate table poller_output;

I found the problem. the poller settings was very strange, in the "Maximum Processes" i had 10 and in "Maximum Threads per process" i had 100. when i chaged it to 5 and 5 cactid works again.

The really strange part is that i havent changed these numbers.

Thanks for the suggestions Witness and a really cool product.

That will do it every time. You only have up to 100 concurrent MySQL connections out of the box and Cactid, would have taken just about all of them.

Hey Devil,

Please check out the post. This is a modified (re-releasable) version of Cactid 0.8.6e. Could you please test.

Hi,

I have the 296 timeout issue... but the parameter in the Thread and process are OK.

But it still not working...
Should I try the 0.8.6e version????

Help will be very appreciated!

Thanks

Please. Once built, run cactid from the command line a few times in DEBUG mode to see if it's running correctly. Then also check the number of records in poller_output table. If you have several thousand, truncate it.
