> The new Protobuf-based client/server operation handlers are not checking to see if memory is low.  For instance, the Java client does this check in handling function execution requests:
> {code}
>         HeapMemoryMonitor hmm =
>             ((InternalResourceManager) cache.getResourceManager()).getHeapMonitor();
>         if (functionObject.optimizeForWrite() && cache != null && hmm.getState().isCritical()
>             && !MemoryThresholds.isLowMemoryExceptionDisabled()) {
>           Set<DistributedMember> sm = Collections.singleton((DistributedMember) cache.getMyId());
>           Exception e = new LowMemoryException(
>               LocalizedStrings.ResourceManager_LOW_MEMORY_FOR_0_FUNCEXEC_MEMBERS_1
>                   .toLocalizedString(new Object[] {functionObject.getId(), sm}),
>               sm);
>           sendException(hasResult, clientMessage, e.getMessage(), serverConnection, e);
>           return;
>         }
> {code}
