Description:
We have RHEL6.2 (kernel-2.6.32-220 or kernel-2.6.32-279) Servers.

After Kernel Patch(kernel-2.6.32-358.2.1 and kernel-2.6.32-358.6.2), We got the 
problem, That is Mysql DB Server's Processs started using Swap Memory.

Not Mysql increase connnect from the WEB or WAS, Not running other processs and Not changed system & application(Mysql) configuration.

Other Servers is no using swap memory after Kernel Patch. 

Only Mysql DB Servers startd using and go on incrase size of Swap Memory.   

I was request for the same Isseue to RedHat GSS  too

Hello Hyoung,

Thank you for the report.
But version 5.5.27 is very old and many bugs were fixed since. Please upgrade to current version 5.5.35/5.6.15, try with it and inform us if problem
still exists.

Thanks,
Umesh
