Hello,

I have a problem with the Cronjob and I can not find what can be blocked.

What can block ?

L'événement de processus de workflow est reporté à l'exécution de la commande cron(4): 8

0 out of 8 processes was finished

I don't found the reason of blocking.

Thank you in advance.

The segfault in the 1st run of the cronjobs will leave some lock files pending.

Subsequent cronjob runs will not do anything for 24 hours. Then they will find the leftover lock files are too old and try to delete them. You can easily delete them by hand, they are in a subdir of var/siteaccess/cache.

Take care about the os users that run those cronjob; Sometimes you might run eg. the cronjobs as root, and leave a stale lock file that cannot be later removed when trying to run cronjobs as another user...
