I am suffering from an "Out of memory" exception in my Windows Service after running it for few hours under huge workload. I used the following performance counters to detect memory leaks:

• bytes in all heap

• Private bytes
• Virtual bytes

The first 2 counters are going up and down regularly ... I cant see anything wrong in them. but the 3rd one is growing very slowly by time, the counter is going up and down t开发者_运维知识库oo but at the end it is increasing by time. What does that mean?

My Win Service is .NET which is calling some functions from a C++ DLL and also using a 3rd party which have some unmanaged code in it.

Does this indicate a memory leak in the managed code / unmanaged code ? or simply this wont help?

Thanks

Take a look at the clr profiler so you can monitor your usage. If it only crashes under hudge load there may not be an error so much as a new design constraint to handle the load.
