Ok, exec-sum then :)

The exact problem is this:

I do a set of calls to convert-and-import-to-sql some big media files
in an upload queue (provided by, going from php_cli ->
php_daemon_script -> php:curl_exec() -> php_script.

php_script at the end does the converting-and-importing for a single media file.
php_script always completes as it should, returning a json status
message back to php_daemon_script

problem is: when processing a 2gb video file, curl_exec() never
returns. verified by a print-to-debug-file statement straight after
the curl_exec() call in php_daemon_script; the debug file never shows.
2gb video conversion takes my pc about 50 minutes to complete.

when processing a 60mb video file, there are no problems whatsoever.

i've used a sniffer app 3 times to confirm that apache does send
packets with the wanted status-update from php_script to
php_daemon_script at the end of processing the 2gb video file, that's
in the php-general mailinglist weblog url.

that's the gist of it, full details on the php-general weblog.
