I am using PhpEd windows version 4.6 build 4621. When I use it to debug long running PHP process, the debugging session always got killed off after 10 seconds or so. The output screen just comes to an abrupt stop, and I can see no further output from the program.

I have changed php.ini to increase the maximum time execution time and argument parsing time to be 3000. Here is the output when I do
php -i |grep max
log_errors_max_len => 1024 => 1024
max_execution_time => 0 => 3000
max_input_time => 3000 => 3000
post_max_size => 8M => 8M
upload_max_filesize => 2M => 2M
debugger.net.maxpacketsize => 4096000 => 4096000
mysql.max_links => Unlimited => Unlimited
mysql.max_persistent => Unlimited => Unlimited
odbc.max_links => Unlimited => Unlimited
odbc.max_persistent => Unlimited => Unlimited
pgsql.max_links => Unlimited => Unlimited
pgsql.max_persistent => Unlimited => Unlimited
session.gc_maxlifetime => 1440 => 1440

The command runs perfectly to the end (takes something like 2 minutes) when I run it through php or php-cgi in dos prompt.

I have no installation of php on the machine other than the one from phpEd. So this shouldn't be a problem.

Can anyone give suggestion how to increase the duration of the debug session?

try max_execution_time => 3000 instead of max_execution_time => 0
