profiling

Hi

I have a net Windows service that is constantly throwing OutOfMemoryException. The service has two builds for x86 and x64 Windows. However on x64 it consumes a lot more memory. I have tried profiling it with various memory profilers. But I cannot get a clue what the problem is. The diagnosis - service consumes lot of VMSize.

Also I tried to look at performance counters (perfmon.exe). What I can see is that heap size is growing and %GC time is 19%.

My application has threads and locking objects, DB connections and WCF interface.

See first app in list
