ok, fully patched, same result. any other thoughts?

i'll also add, running cmd.php on it's own with no parameters seems to work fine, it's only when i run poller.php that it gets into the loop of sql queries.

also, it fails at different points during the poller process it seems. could this be a side effect of a memory issue in the process (keeping in mind i run this with php in a 64mb limit)?

The memory issue should be detected by watching the poller_output table. After polling, it should be empty. IF not, either truncate it or increase php memory size

ok, still stuck on this one, and i have time to address it now.

the poller_output table is completely empty.

RRD's aren't being autocreated.

poller.php is being run as root manually via the command line.

<cacti>/rra was tried with cactiuser's permissions, root's, and 777, still no dice.

just looking at the if statement that is causing this loop of failures:

Code: Select all

 if (sizeof($polling_items) >= $process_file_number
this is obviously the issue i'd presume. is $process_file_number the physical number of RRD files? this is a bad loop if so, since it's not detecting zero files and trying to run since we've told it there's stuff to process AFA sources. strace only shows the "waiting on" lines being written and nothing else when this is happening, so it's definitely that if statement as far as i can tell.

two questions:

1. thoughts on this?
2. thoughts on why .rrd's are not created?

set logging to medium, verify no warning in Settings->Paths, make sure cmd.php is the poller, open a shell, su to root, and run "php -q poller.php". What does your log say? What happened at the command prompt?

i ended up switching to spine. this is running on a VPS, so i think at least part of the issue was memory (even though i have 128 MB and PHP is set to 64MB).

at this point i'm fully up and running.

Make sure that you are running spine 0.8.7a.
