[QUOTE="Berney, post: 1285911, member: 168121"] Hi everyone Doskabouter, I've no experience with memory profilers so know virtually nothing about them. Would you (or anyone else) know how detailed they profile memory, e.g. down to variable level ? If so, would a special build of TVServer be required in order to provide info on the memory locations to the profiler? CyberSimian, Yes it does seems difficult to reproduce the error conditions for the memory leak to become obvious. The original poster seems to me to be so similar as to be identical to my problems, it would be useful to compare notes with the original poster with respect to system setup and tvserver setup this might then provide a clue as to a way to regularly cause the problem and thus can be put under the microscope more fully. I've only got the one windows pc and thus can't setup a test pc. I currently manage the memory leak problem by looking at task manager every day (often multiple times) to see how full memory is. With having removed ETEC scheduled recordings at least if it does crash it will automatically restart the TVServer within a few minutes, whereas before it just locked up and almost impossible to restart with out rebooting the PC, so there has been a work around of sorts that works for me. I plan to study the source code at length in order to understand it as much as I can. I might get lucky and spot the problem, though some how I doubt it. My current thinking is that there are 2 ways the epg is grabbed in the source code and that they conflict with each other, causing memory to remain taken up. I think it would be nice if there was just one basic set of procedures to grab the EPG from a broadcast stream and have that set of basic procedures called as and when needed either while timeshifting/recording or as a regular timed event but undoubtedly there is probably a good reason as to why it is not done that way that I am currently unaware of. I have approximately 420 scheduled recordings setup, they are currently a mixture of single and ETTC. I'm very busy over the next 3 weeks so I'll not be able to devote much time to the problem. However this nemory leak does irritate me and I will be keeping an eye open on this forum thread for any ideas that people might have. Btw the second way the EPG is grabbed is in the source file 'TimeShiftingEPGGrabber.cs' should anyone care to take a look at it. [/QUOTE]
