symfony2 gearman worker stop when clearing the cache - php

Question

I implementing Mmoreram gearman bundle in my symfony(2.4) project.
I have website that users make action and triggers jobs.
like:
# Get Gearman and tell it to run in the background a 'job'
$id = $this->params['gearman']->doHighBackgroundJob('MYBundleServicesPublishWorker~publish',
json_encode($parameters)
);
And i have one worker that run infinitely and do the jobs (iterations: 0)
I run it from command line once in background:
nohup php /myproject/app/console gearman:worker:execute MYBundleServicesPublishWorker > /tmp/error_log.txt > /tmp/output_log.txt &
The config look like:
gearman:
# Bundles will parsed searching workers
bundles:
# Name of bundle
MyBundle:
# Bundle name
name: myBundle
# Bundle search can be enabled or disabled
active: true
# If any include is defined, Only these namespaces will be parsed
# Otherwise, full Bundle will be parsed
include:
- Services
- EventListener
# Namespaces this Bundle will ignore when parsing
ignore:
- DependencyInjection
- Resources
# default values
# All these values will be used if are not overwritten in Workers or jobs
defaults:
# Default method related with all jobs
# do // deprecated as of pecl/gearman 1.0.0. Use doNormal
# doNormal
# doBackground
# doHigh
# doHighBackground
# doLow
# doLowBackground
method: doNormal
# Default number of executions before job dies.
# If annotations defined, will be overwritten
# If empty, 0 is defined by default
iterations: 0
# execute callbacks after operations using Kernel events
callbacks: true
# Prefix in all jobs
# If empty name will not be modified
# Useful for rename jobs in different environments
job_prefix: null
# Autogenerate unique key in jobs/tasks if not set
# This key is unique given a Job name and a payload serialized
generate_unique_key: true
# Prepend namespace when callableName is built
# By default this variable is set as true
workers_name_prepend_namespace: true
# Server list where workers and clients will connect to
# Each server must contain host and port
# If annotations defined, will be full overwritten
#
# If servers empty, simple localhost server is defined by default
# If port empty, 4730 is defined by efault
servers:
localhost:
host: 127.0.0.1
port: 4730
doctrine_cache:
providers:
gearman_cache:
type: apc
namespace: doctrine_cache.ns.gearman
my problem is when i run app/console cache:clear and after that job come in the worker crash
its throw error :
PHP Warning:
require_once(/myproject/app/cache/dev/jms_diextra/doctrine/EntityManager_53a06fbf221b4.php):
failed to open stream: No such file or directory in
/myproject/app/cache/dev/appDevDebugProjectContainer.php on line 787
PHP Fatal error: require_once(): Failed opening required

(include_path='.:/usr/share/php:/usr/share/pear') in
/myproject/app/cache/dev/appDevDebugProjectContainer.php on line 787
How can i fix it, i try to change the doctrine bundle cache type: file_system/array/apc
but it did not help
How can i overcome this?
what i am doing wrong?
Thanks in advance

Answer 1

i found the problem, i have in my worker this line :
$this->doctrine->resetEntityManager();
that cause this,
now i am only open connection and close it like:
$em = $this->doctrine->getEntityManager();
$em->getConnection()->connect();
# run publish command
............
# close connection
$em->getConnection()->close();
