PHP.EXE open dozens of times

Post by BSOD2600 »

I woke up this morning to find my Cacti server practically unresponsive. Upon further investigation, I saw 100+ instances of php.exe running which was consuming ~80% CPU.

Image

When logging onto the server, I could see several of the following messages on the dos cmd.php windows:

Code: Select all

ERROR: illegal attempt to update using time 1105711803 when last update time is 1105712103 (minimum one second step)
OK
OK
Content-type: text/html
X-Powered-By: PHP/4.3.10

01/14/2005 06:24:58 AM - POLLER: Poller[0] Maximum runtime of 296 seconds exceeded. Exiting.
Anyways, after restarting IIS, it appears the server and poller is back to normal. Is this the type of problems people have been having with PHP 4.3.10 ?

Crap, well it's not a php 4.3.10 issue. I went back to 4.3.9 and the same thing happened again! Now what can I do to find out why the heck the processes are not closing?

What is your Cacti version? How many rows do you have in the poller_output table?

I too, am having this problem. Not so bad, it doesn't seem to happen each cycle, but gradually my process table is filling with php.exe and cactid.exes.

I am running w2k3, iis6, php 5.0.2 (was running 5.0.3, but per our guru's advice, dropped back to 5.0.2. Seems better, but not fixed.), mysql 4.0.20, rrdtool 1.0.48.

did not have this problem with php 4.3.8.

my poller_output table is empty.

I have some errors mentioning re-caching, but that's about it.

Cacti version 0.8.6c, php 4.3.9, win2k3.

There appears to be 4 rows in poller_output (viewed with phpmyadmin):
local_data_id, rrd_name, time, output

I'm going to switch from cmd.php to cactid.exe and see how that does for a while. Odd thing I've already noticed is that it does not create the log, even though I've got it set to in cactid.conf.

The logfile setting in cactid.conf is ignored in 0.8.6. It is taken from Settings->Paths in 0.8.6.

If thats the case, cactid does not properly use it (my log is blank still). I've got it set to: ././log/cacti.log which works fine with cmd.php.

Specify the full path, such as /usr/local/..

webroot: C:\Auntie\cacti\
Log: C:\Auntie\cacti\log\cacti.log
Cactid: C:\cactid\cactid.exe
rrdtool: C:\rrdtool\rrdtool.exe


Is the log path, basing itself off where the poller lives. Meaning, since cmd.php lives in: C:\Auntie\cacti\, the log path: ././log/cacti.log works fine. But when I'm using cactid, that log path is not valid. If this is the case, is there a global name, like <path_rra> which I can use so the log file is always defaulted to the same location, regardless of which poller is being used?

edit:
Well I tried to use the path: <path_cacti>/log/cacti.log for the log. but it didn't work. Got the following errors when I went to use the system utils -> View Cacti Log File:

Code: Select all

Warning: touch(): Unable to create file <path_cacti>/log/cacti.log because Invalid argument in c:\auntie\cacti\utilities.php on line 107
Warning: file(/log/cacti.log): failed to open stream: Invalid argument in c:\auntie\cacti\utilities.php on line 108

Well after using cactid for a day instead of cmd.php, the problem with these processes running away is still present:

I'm going to drop the issue about the log file. Going back to cmd.php for now.

How can I find out why all of these php processes don't end up closing and eventually kill the computer?

What is the length of you polling cycle?

And what is the interval which you are polling on?

The following is when there are no errors or extra php processes running:
SYSTEM STATS: Time: 47.9460 s, Method: cmd.php, Processes: 2, Threads: N/A, Hosts: 11, Hosts/Process: 6

Polling every 5 minutes. This problem with extra processes just started 3 days ago, and I don't recall making any system changes, EXCEPT installing PHP 4.3.10. After a day, I went back to 4.3.9. If I type php -v at the commandline, it does say I've got 4.3.9 too.

I think this might be a Win2K3 problem. I got to looking at the number of connections that were made when the server would choke. Turns out there is a shitload! Disable and re-enabling the NIC fixes the connection problem. I also can see that the when this problem is happening, the cmd.php window will get through some clients and then just hang.

All the connections at the time the problem is occuring:

Keep track of this thing and then let me know if it's occuring in cmd.php, cactid, or both.
