Hi Support,

I used Mod gearman2 to build my monitoring system which ran quite well till this afternoon. suddenly, one site went down. I check the error log /var/log/message and /var/log/mod_gearman2. and found below error. Can I seek your help on this

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:

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.
