Garbage Collection every 100 seconds

Question

Did any one encountered a scenario where application under high memory allocation load performed second generation collection every 100 seconds ?

We using 64-bit server

Answer 1

That the garbage collector is being invoked frequently is not in itself necessarily a huge issue - it could however be a flag that you are not optimally handling your memory well (for instance not passing massive strings by reference into methods).

Garbage collection should be non-deterministic. That noted, if you are running a number of critical tasks, but your thread(s) are sleeping at some juncture (like every 100 seconds) it is reasonable that the garbage collector may take the opportunity to collect at that point. More likely is that the consumption due to allocation peaks at more-or-less regular intervals and the garbage collector is invoked to retrieve unused memory.

I highly suggest profiling the memory consumption of your application.
