#25325 [Fbk]: command from exec do not migrate in an openMosix cluster

ID: 25325 Updated by: derick@php.net Reported By: carb at videotron dot ca Status: Feedback Bug Type: Filesystem function related Operating System: RedHat 9.0 PHP Version: 4.3.3 New Comment: Why do you think this is related to PHP? PHP does *nothing* special with processes... I wonder how this can be related to OpenMosix.

Running "awk 'BEGIN {for(i=0;i<10000;i++)for(j=0;j<10000;j++);}' > /dev/null 2>&1 &" from a command line several times creates processes that get migrated. Running the same thing several times from an exec in a PHP script does not get migrated. The same problem occurs whether the script is executed from apache "http://localhost/test.php/" or the command line "php test.php" Reproduce code: --------------- <?PHP exec("awk 'BEGIN {for(i=0;i<10000;i++)for(j=0;j<10000;j++);}' > /dev/null 2>&1 &"); ?> Expected result: ---------------- When executing the script several times in an openMosix cluster, some of the processes should migrate. Actual result: -------------- When executing the script several times in an openMosix cluster, none of the processes migrate. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25325&edit=1
