Some vendors say that several correctable errors during a certain period of time is of no harm. For example, Oracle says replace a DIMM when one of the following events takes place: More than 24 Correctable Errors (CEs) originate in 24 hours from a single DIMM and no other DIMM is showing further CEs. The DIMM fails memory testing under BIOS due to ...

You can try using passe-partout. I have successfully used it with Apache, not with Tomcat, but it's advertised to work with Tomcat 7.0.34 + apr 1.4.6 + jdk7-openjdk 7.u9.

Rob-d mentions that load-balancers must perform health checks on the backend servers to ensure they're healthy and can serve requests. This is absolutely true and I think it's what would enable you to do what you want (checking other metrics and having the LB make routing choices based on those). Assuming you're load-balancing HTTP, most load-balancers will ...

The question you're asking is an extremely important question in relation to load balancing, there are Two primary reasons why we load balance, first and most obvious is to split client requests to 2 or more servers, second to make that service highly available. Having configured the load balancer with these two outcomes in mind we then enter into the realm ...

Typically the loadbalancing component of the loadbalancer is only only aware of either the number of active network connections and/or requests it has sent to a back-end server and knows nothing of the actual load those generate on the back-end system. The load balancing algorithm you select determines which back-end server will handle the next new ...

It is important to map the csrow and channel to physical slot/DIMM and replace ASAP. In my experience you will start to get more and more errors but it all depends on how fast the chip goes totally bad, I have seen it progress from a few errors a day to dead the next day or it could make it for several months or more (all depending on your workload). ...

For those who end up here with something similar: in the end it was unmanaged code in the Active Directory libraries of the .net framework that was not disposed correctly. That's why the unmanaged heap was so large. How did I find out what was the culprit? I just ended up looking at random memory addresses to find out what the contents was. And since I ...

Maybe you have crashkernel enabled on your CentOS instances. It basically reserves a portion of your memory to boot a, well, "crash kernel" in the case the main kernel crashed/deadlocked. Please show the output of cat /proc/cmdline to verify. UPDATE: Regarding the other 200 MB "lost", it seems from /proc/meminfo that they are reserved for use by the PCI ...

The exact answer will depend on the workload. Performance If you get another VPS with the same specs as the first, you will have twice the memory, twice the CPU, twice the disk, and twice the network. If you are able to utilize all those resources, you may get better performance from two VPS than doubling just the memory of your current. However if you ...

It looks like a 32bit kernel with centos.

I hate when people don't provide all relevant details. Let's assume the server is a DL360 G6 or G7. If that's the case, there are specific DIMM population guidelines for those models. If you have ILO access to the server or even the specific model or a way into the existing operating system, you could see the layout and options. But really, use RAM ...

I agree with Joel. Return the single dimm and order your own after you lookup exactly what is needed. Meaning no your idea will not work. You need to physically balance the number of modules between the two procs.

This is an older post but I figured I could help someone out with this post. First, the screenshot is only of the scraper server responses, that will not help too much from my perspective trying to answer, however, I have been there before. I am taking it that your node/express scraper and your node/express/angular app are on the same hardware/shared ...

I guess you're out of luck. Why can't I get a larger heap with the 32-bit JVM? The maximum theoretical heap limit for the 32-bit JVM is 4G. Due to various additional constraints such as available swap, kernel address space usage, memory fragmentation, and VM overhead, in practice the limit can be much lower. On most modern 32-bit Windows ...

Ideally replace the DIMM in slot F2/2 - but if you're not too worried about it then perhaps a full power-off and restart could clear the error - I'd still want to replace the DIMM though.

This can not be answered because it depends on what you do application wise. Generally on an application level you do not care about those - you care about application level metrics (average response time per request, to be "simple").

Those metrics are mostly for OS developers: if you want specu=ifically to know about cpu and memory, then you want cpu-seconds actually used vs load, memory vs load, and io to the paging device vs load The first will rise to your capacity, then plateau The second will rise, start to plateau, and then the third will show a step upwards at that same load. If ...

back in the early 2000's I worked at a company with lots of Color Laser Printers, Plotters, and other kewl print devices. We had one that was upgraded to 128 MB of ram.. Their was no speed difference that I could see. However one of the graphics designers used to print huge images(High DPI or lots of Vectors). Before the upgrade he would always complain ...
