This is an informative message returned by the Tomcat web server (AhsayCBS version 8 is bundled with Tomcat version 8.5.34, whereas AhsayCBS version 7 is bundled with Tomcat version 7.0.81).
Even though the message say GC (Allocation Failure), but it actually indicates that the GC (Garbage Collection) process was completed successful.
Administrator can safely ignore the message, no user interaction is required.
