I will take a look at ADP. I have to find some time to set it up. In the mean time does anybody have any ideas why the same script could be running at less than 0.4 seconds and then jump to 32 seconds then go back to normal? It isnt just this script. It happens with others. Not at any kind of interval either. Any brainstorms would be helpful, I have been racking my brain trying to think of any reason for this. Thanks Charles Killmer Previous Comments: ------------------------------------------------------------------------ [2002-01-10 22:39:25] [EMAIL PROTECTED] Try APD to make sure if this is PHP or your script fault. http://apd.communityconnect.com/ (APD supports tracing script execution) You need UNIX like OS ;) Try Linux :) ------------------------------------------------------------------------ [2002-01-10 16:45:23] [EMAIL PROTECTED] This is a snippet from the performance log on Jan 10 2002. Notice that this script usually takes 0. some seconds. But one of these took 31.9 seconds. This happens periodically on our busiest sites. This file only includes on file with a few functions. Executes two of those functions. One just creates a menu using a few if statements. The other simply outputs some html. function stuff() { ?> html stuff here <?} Date Time File File Execution Time Browser Agent 01/10/2002 01:10:50 Z:\Sites\Client1\samePhpFile.php 0.062487006187439 Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0) 01/10/2002 05:48:27 Z:\Sites\Client1\samePhpFile.php 0.061802983283997 Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; Q312461) 01/10/2002 06:01:47 Z:\Sites\Client1\samePhpFile.php 0.082913994789124 Mozilla/4.0 (compatible; MSIE 5.5; Windows 98; Win 9x 4.90) 01/10/2002 06:35:45 Z:\Sites\Client1\samePhpFile.php 0.068187952041626 Mozilla/4.0 (compatible; MSIE 5.5; AOL 5.0; Windows 98; Win 9x 4.90) 01/10/2002 07:19:53 Z:\Sites\Client1\samePhpFile.php 0.05417799949646 Mozilla/4.74 [en] (Win95; U) 01/10/2002 08:41:42 Z:\Sites\Client1\samePhpFile.php 0.24766898155212 Mozilla/4.73 [en] (Win95; U) 01/10/2002 09:24:06 Z:\Sites\Client1\samePhpFile.php 0.39544701576233 Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; Q312461) 01/10/2002 09:24:17 Z:\Sites\Client1\samePhpFile.php 0.28285801410675 Mozilla/4.0 (compatible; MSIE 6.0; Windows 98; Q312461) 01/10/2002 09:36:11 Z:\Sites\Client1\samePhpFile.php 0.048995971679688 Mozilla/4.0 (compatible; MSIE 6.0; AOL 6.0; Windows NT 5.1) 01/10/2002 09:55:23 Z:\Sites\Client1\samePhpFile.php 0.050058960914612 Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 4.0) 01/10/2002 10:21:52 Z:\Sites\Client1\samePhpFile.php 0.068014025688171 Mozilla/4.0 (compatible; MSIE 5.5; AOL 7.0; Windows 98; Win 9x 4.90) 01/10/2002 10:31:00 Z:\Sites\Client1\samePhpFile.php 0.07217800617218 Mozilla/4.0 (compatible; MSIE 5.5; AOL 7.0; Windows 98; Win 9x 4.90) 01/10/2002 10:55:43 Z:\Sites\Client1\samePhpFile.php 0.048286080360413 Mozilla/4.72 [en]C-BMY (WinNT; U) 01/10/2002 11:01:39 Z:\Sites\Client1\samePhpFile.php 0.062674999237061 Mozilla/4.72 [en]C-BMY (WinNT; U) 01/10/2002 11:05:08 Z:\Sites\Client1\samePhpFile.php 0.068107962608337 Mozilla/4.0 (compatible; MSIE 5.01; Windows NT) 01/10/2002 11:10:43 Z:\Sites\Client1\samePhpFile.php 0.13118100166321 Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt) 01/10/2002 11:11:37 Z:\Sites\Client1\samePhpFile.php 0.36615908145905 Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0) 01/10/2002 12:18:57 Z:\Sites\Client1\samePhpFile.php 0.12750899791718 Mozilla/4.0 (compatible; MSIE 5.5; Windows 95; SNET) 01/10/2002 12:26:46 Z:\Sites\Client1\samePhpFile.php 0.031258940696716 Mozilla/4.0 (compatible; MSIE 5.0; Mac_PowerPC) 01/10/2002 12:57:43 Z:\Sites\Client1\samePhpFile.php 0.12115907669067 Mozilla/4.72 [en]C-BMY (WinNT; U) 01/10/2002 14:16:14 Z:\Sites\Client1\samePhpFile.php 0.098912000656128 Mozilla/4.0 (compatible; MSIE 5.01; Windows 95) 01/10/2002 14:28:04 Z:\Sites\Client1\samePhpFile.php 0.3418220281601 Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; MSN 6.1; MSNbBBYZ; MSNmen-us; MSNc11) 01/10/2002 14:28:57 Z:\Sites\Client1\samePhpFile.php 31.927405953407 Mozilla/4.0 (compatible; MSIE 5.0; Mac_PowerPC) 01/10/2002 14:36:57 Z:\Sites\Client1\samePhpFile.php 0.35919499397278 Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; MSN 6.1; MSNbBBYZ; MSNmen-us; MSNc11) 01/10/2002 14:41:49 Z:\Sites\Client1\samePhpFile.php 0.048683047294617 Mozilla/4.0 (compatible; MSIE 5.5; AOL 6.0; Windows 98; Win 9x 4.90) ------------------------------------------------------------------------ [2002-01-08 15:38:51] [EMAIL PROTECTED] I work for a company that has around 20 sites using PHP. Lately I have been tracking some odd script timeout problems. None are related to bad code or database connectivity. I started doing some extensive logging and have a report that shows that every timeout that I checked followed a pattern. This is just a section of the log file I am looking at Date Action # of processes running . . . 1/4/2002 21:41:37 EndSomeOtherRequest 0 1/4/2002 21:41:59 Start1 1 1/4/2002 21:42:14 Start2 2 1/4/2002 21:42:14 Start3 3 1/4/2002 21:42:14 End 2 2 1/4/2002 21:42:14 End 3 1 1/4/2002 21:42:23 Start4 2 1/4/2002 21:42:23 End 4 1 1/4/2002 21:42:27 Start5 2 1/4/2002 21:42:27 End 5 1 1/4/2002 21:42:39 Start6 2 1/4/2002 21:42:39 End 6 1 1/4/2002 21:42:46 Start7 2 1/4/2002 21:42:46 End 7 1 1/4/2002 21:42:48 Start8 2 1/4/2002 21:42:54 End 8 1 1/4/2002 21:42:59 End 1 0 . . . The one that started first, finished last. That script usually takes less than zero seconds. Though this time it took 60.014 seconds. Our script timeout is set to 240 seconds right now so we can capture these script durations. This happens at all times of the day. No apparent pattern, other than that the one that takes an extrodinary time to complete is consistently the first one in this block of processes. And it always finishes last, but that is less startling because it takes so long to finish.
