php set_time_limit（）在php-fpm上生成超时

I have a strange issue with php-fpm and set_time_limit(). After i upgraded php at all to 5.6.30 a previously worked script dies with timeout.

<?php
set_time_limit( 300 );
echo "ok";

The result is:

( ! ) Fatal error: Maximum execution time of 30 seconds exceeded in /var/www/hutml/asd.php on line 2
Call Stack
#   Time    Memory  Function    Location
1   0.0002  238976  {main}( )   .../asd.php:0
2   0.0004  239616  set_time_limit ( )  .../asd.php:2

The interesting part is if i restart php-fpm it works for a few requests (3-8) and than stops working forever (till next restart).

Here is the trace where it not works:
