Lynn: Since the computer is not connected to the network, there should be little potential for evil except that which I generate myself! The major evil is the power that it draws! Tom and Guy: It certainly begins to sound as if the drivers are at fault. I formerly ran the program on my old XP machine with no problems, although I don't really remember if I gave it the "24 hour stress test". But that machine is too slow to use all the programs I want to use. But, Tom, I don't think it is memory leak, since running Task Manager and looking at the memory usage, I get a steady value around 1.1 GB for everything that is running, and this value does not change over 24 hours. Curiously, however, NaP3's CPU usage shows big spikes about every 20 seconds, going from ~20% to about 60% and back again. Both processors do this in parallel. This is not a LPB problem, however, since LPB shows a steady, low usage if NaP3 is not running. So, with a big thanks to everyone who replied, I will take the easy way out and shut down the computer at night. Maybe some day I will understand enough to use a different cure. 73 - George, W3HBM On 12/6/2016 2:07 PM, Lynn W.

Re: [Elecraft] Fwd: Re: LP Bridge crashes with K3
Hi George, I have to agree with Tom on this one, either suspect drivers, or some as yet undiscovered conflict running on your PC. The slowdown you describe is a dead giveaway. That the dying program sends some garbage to the K3 as it expires is irrelevant. Whatever the program/driver is the problem, it's now so lost in itself that it has called for a writeout to an external device when there is no data to send. It has clearly lost its mind. A common bug in a poorly written program is called a "memory leak". That is where a program allocates a certain amount of memory for a transient task, and when the task is done, does not release all the memory back to the "memory pool". This causes available memory to creep down until there is not enough to run. The offending program often crashes, because the same stinky programming causing the memory leak also does not provide a smooth shut down at out of memory with meaningful messages to inform which program is exiting and why. There are variants of this malady, like the one where the program assigns a FIXED large buffer to a usage, and then exhausts it in the same manner. This is a lazy solution to a memory leak that they can't find, hoping to crash just the program and not the operating system. Sometimes these buffers are without boundary code which detects end of assigned space and gracefully exits with understandable messages. The stinky code then proceeds to gradually *overwrite its own program instructions* until it encounters code it is actually running and then it simply goes insane. This is possibly a blue screen or PC hang moment, though later OS are getting better and better at trapping code like this. Outward symptoms to the PC user could be anything. There are other specific kinds of stinky programming that present in the same "What the h*ll is that?" fashion. But there is a way to spy on this stuff as it runs. You run a CPU monitor that displays what is going on in the PC. One of the displays will be active memory, Possibly called memory set, listed by program. Sort on this column and then watch stuff on your system. Often the offending program sticks out like a sore thumb. There may be multiple issues that point to conflicts among things you run at the same time. A better good and free monitor, can be found at https://technet.microsoft.com/en-us/sysinternals/bb795533.aspx. On the upper right of this page, under Top Ten Downloads, download Process Explorer and install. This well done monitor does not suffer from a lot of the clunkies that the Microsoft monitors and some of the other 3rd party monitors seem to have. The only complaint I have ever had about it is the default color line of black text on dark grey or purple for suspended processes and packed images. Those can be easily fixed in menu bar>options>configure colors, which also has the color code for what kind of thing each color is. Click on the column headers Working Set, CPU, and CPU Time. Here you can remove or add types from the display by checking or unchecking the line. I would expect Windows 7 should run Process Explorer just fine, though currently I only have an ancient laptop with XP and all else is upgraded to Windows 10 Pro, which at this point seems the best OS Microsoft has ever written. If you really like it, in Windows 10 you can do Process Explorer>menu bar>Options>Replace Task Monitor. I think MS bought it and at some point will simply replace their "Resource Monitor" with this one. It's not yet time to disassemble your K3 and send the pile of pieces back to Watsonville. Let us know what you find spying on stuff. 73 and for sure Good Luck Guy K2AV On Tue, Dec 6, 2016 at 3:21 PM, Tom wrote: > Honestly, I don't believe this is an issue with LPBridge but rather Eltima > drivers.

Re: [Elecraft] Fwd: Re: LP Bridge crashes with K3
Honestly, I don't believe this is an issue with LPBridge but rather Eltima drivers. I can run the Eltima serial port monitor and even without traffic it will always crash after a number of hours. Always. There is not much that can be done other than rebooting after some time or closing it all when you are not using it. 73 Tom -Original Message- From: George Kidder Sent: Tuesday, December 6, 2016 1:37 PM To: 'Elecraft Reflector' Subject: [Elecraft] Fwd: Re: LP Bridge crashes with K3 Larry and all, I have now tried adjusting the buffer settings.

I next tried the "correct connection problems" setting, full left (1) on each.

I've tried everything I can think of, and am now looking for some additional thoughts.

Larry and all, I have now tried adjusting the buffer settings. Originally, they were set full "right" (High, 14 for receive, High 16 for transmit) I moved the sliders to about 3/4 of full scale - still got a LPB crash in about 7 hours, while running NaP3 and FLDigi through LPB. I next tried the "correct connection problems" setting, full left (1) on each. This time it ran more than 3 but less than 20 hours (overnight run) and while LPB did not crash, NaP3 did, which requires complete computer reboot.
