PHPSVR: ERROR: only when running with 1 process (cmd.php)

[dreness]

I'm getting PHPSVR: ERROR: Input Expected, Script Server Terminating, but only when I run with 1 cmd.php process. With 2 or 3, the error does not occur. In all cases, all of the data I'm asking for is actually being collected; no holes in the graphs or anything. This started happening after I added a couple more custom scripts to my snmpd configurations (and their accompanying data sources / graph templates), all of which execute normally when invoked by hand. I can see the return values in the debug log, and they all look fine.

I followed some other suggestions like looking for errant data sources by setting the host filter = none; there aren't any. I've enabled debug logging, and the error would always occur at about the same point in the polling sequence, so I examined the polling configuration of the host being polled at the time of the error and compared it to other hosts that should have identical configuration. e.g.

Code: Select all

mysql> select rrd_name,arg1 from poller_item
    -> where hostname = "scv03.apple.com" order by local_data_id;

All of the relevant configurations match, and again, all the data I'm asking for shows up in the graphs.

Any suggestions on how to troubleshoot this? I'm perfectly content to leave it set for 2 processes, but ... I don't like it when things aren't working perfectly

I also tried using the patched cmd.php mentioned in another thread; that didn't help. I'm using cacti-0.8.6f.

Thanks!

PHP 4.4.0 is out and works with cacti 0.8.6f. You'll also need to upgrade Zend (1.3.0 is not the version you're running anyways, thats just the engine).

Yeah... Mac OS X 10.3.9 isn't exactly current. I had initially tried to deploy this in tiger (10.4), but got stuck by the mysql auth problem. I've since learned about the workaround, so I'll probably end up rebuilding it all in 10.4.2 Server.
