Previous Comments: ------------------------------------------------------------------------ [2007-11-26 23:15:41] development at domain51 dot com I just ran into this issue as well... I was testing PHP's speed at forking N processes and I hit an issue where the OS wasn't able to fork any more processes. Instead of getting a -1 response, the code referenced below triggers a fatal error and halts PHP. In other words, the check on line 227 referenced by trot at plotinka dot ru should be deleted. "-1" is a valid return value and should not trigger an error any failure is encountered during the fork. ------------------------------------------------------------------------ [2007-11-26 12:46:57] trot at plotinka dot ru Fatal error on failure. But in manual: "On failure, a -1 will be returned in the parent's context" http://php.net/pcntl_fork thx ------------------------------------------------------------------------ [2007-11-25 17:32:14] jani@php.net Exactly what are you reporting here?
