How to identify problem remotely

Recommended Posts



There is a Win32 application used on a client. They face problem of "application freezing" randomly. Same binary is used in more than a single machine and this is the only machine having problems.


That was not my decision, but customer could do it and they formatted the complete system, install Windows from scratch. That did not help. Since it is random (sometimes days of smooth running), I think remote debugging is not very useful here. Or, is it the only option?


I would like to at least get a call stack when that freezing happens (they kill the application using task manager when that happens).


Any help is appreciated.


Thanks & regards,

My first suggestion would also be madExcept.  Aside from that, in the task manager (on Win10) you have two options that might help: "Analyze Wait chain" and "Create dump file".  The latter will dump the application image.  The image may be inspected with e.g. WinDbg.  Here's a bunch of tutorials: https://marc.durdin.net/2015/11/windbg-and-delphi-a-collection-of-posts/ And though it's .Net based and a little old this seems interesting: http://alookonthecode.blogspot.com/2012/02/windbg-101a-step-by-step-guide-to.html And this: http://capnbry.net/blog/?p=18

Based upon your statement that it's the same binary but it only freezes on one machine would make me focus on a hardware issue first.  Perhaps bad RAM, overheating CPU, etc.   Back in the day there were hundreds of thousands of PCs with faulty capacitors from most major manufacturers and over time the capacitors failed.  The result for our Delphi app was it crashed and became unstable on those machines.  It took us quite some time to figure out this cause.

Hello @ertank


is it possible that on that machine are presents different parameters or configuration files that may cause the problem?


How many times the problem appear? Becasue, in my experience, if the problem is on the RAM module you should get a lot of problems... and not only on your application.

Anyway, get any linux distro and test the RAM or get this one (https://www.memtest86.com/)
