Hi Support,

Thanks for the helpful error logs! :)

Looks like the mod_gearman worker is crashing. What version of mod_gearman2 is running on the worker machine?

Please post the output from the following command:

Code: Select all

rpm -q mod_gearman2

Thanks a lot. I attached the result.

Shall I remove the existing mod gearman and reinstall it?

Unfortunately Mod Gearman is a third-party product and CentOS 6 is no longer supported.

The double free corruption error is likely due to a bug in Mod Gearman (See changelog).

Perhaps you could try upgrading mod gearman on the machine.
