When you do not pass "-l release=precise" or "-l
release=trusty" to jsub, the grid assumes that the job will
run on both releases and chooses one by availability.  In
your case, it has picked Ubuntu Precise ones ("qacct -j
cron-tools.hay-1"; host names with numbers "-12xy" are Pre-
cise (Ubuntu 12), "-14xy" mean Trusty (Ubuntu 14)).  Precise
has PHP at:

| PHP 5.3.10-1ubuntu3.21 with Suhosin-Patch (cli) (built: Oct 28 2015 01:43:56) 
| Copyright (c) 1997-2012 The PHP Group

|     with Xdebug v2.1.0, Copyright (c) 2002-2010, by Derick Rethans

To ensure that your job runs (only) on Trusty and thus:

| PHP 5.5.9-1ubuntu4.14 (cli) (built: Oct 28 2015 01:34:46) 
| Copyright (c) 1997-2014 The PHP Group

|     with Xdebug v2.2.3, Copyright (c) 2002-2013, by Derick Rethans

add a "-l release=trusty", i. e.:

> 0 * * * *  jsub -N cron-tools.hay-1 -l release=trusty -mem 700m php /data/project/hay/lib/crawl-tools.php
