The same problem happens for me on PHP 5.2.6 / Apache 2.2.9, Apache won't run any PHP after I try an exec/passthru/`` -no matter what command I try. Only way to get PHP back seems to be closing all browser windows that point to my server and waiting for a while before trying to use a PHP page again. Previous Comments: ------------------------------------------------------------------------ [2008-09-15 17:01:02] vlabella at uamail dot albany dot edu We have been having the same issue for a long time on win2003 with php version 5.2.X and apache 5.2.x calling both perl scripts and .exe with the exec fuinction. We found that it mostly happens when php runs exec concurrently on the same process. For example we would have ajax call do an exec on the server to read some data and feed it back to the user every 5 seconds. In addition the user could do an ajax call to do something as well on this page. if the user call came at the same time as the schdeduled call then php would hang and we would have to restart apache. We found it also happens on pages where there are multiple exec() calls. We find that all the scripts and programs we call run fine its just that php hangs when they finish for some reason. We have our max_execution_time set to 30 minutes so its not a timeout issue. We found that calling session_write_close(); before each exec call seemed to resolve this issue. But we are not really sure why and what other effects session_write_close(); may have on other processes. Hope this helps resolve this issue. it is a major headache for us for the past 2 years!! ------------------------------------------------------------------------ [2008-08-08 18:55:29] jumpbackhack at gmail dot com this is still a bug. this is not an apache issue as I have tested various versions ranging from 2.0.x to 2.2.x I have tested php v5.2.6 and even a late development version. This happens on linux OS as well even with shell_exec() would there be a backtrace on a hang? it appears that the hang happens after a successful script executes, the following time the script runs there is the hang. usually lasts 2-5 minutes before it allows apache to run any php again. note that apache will serve static/html files without issue while any php files are not called. even a restart of apache does not resolve. ------------------------------------------------------------------------ [2008-07-22 01:00:01] php-bugs at lists dot php dot net No feedback was provided for this bug for over a week, so it is being suspended automatically.
