Problems with mod_gearman 3.0.5, gearman stuck after some hours/mins (nagios 4.3.4)

[Chaos Nagios]

Hi, 

I have a problem with gearmand v1.0.6 (ubuntu 16.04) and mod_gearman 3.0.5 with nagios 4.3.4, the problem is that when pass some hours (and some times a few minutes) the gearmand gives the error " interrupted system call" and stop processing checks from nagios.

I found a workaround that reboot the gearmand daemon every hour, but I need to know what could be the problem.

Any suggestion?

Thanks.
