#16325 [Com]: Memory leak causes DLLHOST to become large

ID: 16325 Comment by: fer at onplaza dot com Reported By: mail-php dot net at kimihia dot org dot nz Status: No Feedback Bug Type: IIS related Operating System: Windows 2000 Server PHP Version: 4.1.2 New Comment: Same as others, normally HOSTDLL.EXE grows between 1-2 Mb per request. I've stopped all the rest of services, created a phpinfo.php whith only the named function and a phpinfo.htm; both in the same directory, and if only happens when calling the .php extension page. That's why I think that in this case we are not in front of an IIS problem. Looks like a big leak of memory that in some cases php is unable to handle This is my 6'th year using PHP. Fer Previous Comments: ------------------------------------------------------------------------ [2003-04-21 07:25:24] nicolai at petri dot cc This happens also for me with both php 4.3.1 and 4.3.2 RC1. It also happens even if I don´t load any extensions, so the leak seems to be in the core php stuff. I tested with my own pages and phpinfo() pages. Each hit generates 2-3 Mb. of mem. leak. Another (maybe related) observation i did, was that when I run with mssql extension and use pconnect calls.. phpinfo() always shows 0 connections and 0 persistent connections. So maybe php cannot locate it's runtime datastructures and re-allocates them on each hit ? I cannot compile php from sources. But if anyone can point me to a debug build I can try that with memleak detection on.

I'm running on Windows 2000 Advanced Server with IIS 5.0. I recently moved to ISAPI instead of CGI as I upgraded from 4.2.1. A week ago I noticed extreme RAM usage. The sites on the server only have < 50 hits / day, so the bug does not require heavy load to appear. I tested it on a page showing phpinfo() and it added 1-2 MB per request. Restarting IIS frees the memory, but that's not really an option. I've tested the latest CVS snapshot and it appears to have the same bug. ------------------------------------------------------------------------ [2002-10-26 01:00:06] php-bugs at lists dot php dot net No feedback was provided for this bug for over 2 weeks, so it is being suspended automatically.

During 2 seconds 300 MB of RAM where reservated for the service. I had to stop and restart all services and IIS admin to get the memory back. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
