No, PHP timeout more likely (MAX_EXECUTION_TIME in php.ini)

If safe_mode is NOT enabled on your server you can change the time limit
from within the script itself, using set_time_limit(seconds). If it IS
enabled, there is no way to circumvent the preset time limit.

If you have write access to php.ini you could start by setting a higher
execution time limit. If that is not the case you probably aren't
allowed to start other processes on the server either...
Otherwise you could consider writing the calculations app in C++, Perl
or Tcl or Bash scripting or what have you and spawn the process from the
PHP script. Email should be sent from that separate app in this case.
