java program hangs
Dear all,
I have a java program (simulation program) that has extensive computation and storage of objects in trees and arrays. It usually runs in a few hours. Recently, after I made few modifications, I found out that the program hangs for some time. I tried to run it on different machines and it hangs (at diiferent places in the code as indicated by my log file).
I looked at the processes in the task managere and I see the memory usage column is decreasing from 300,000s to 14,000 (so far). The cPU column is around zero and the System Idle process is 98%
Any idea? why my programs hangs for all this time. Somebody told me that it is gabage collection....
Thanks in advance
I doubt it is garbage collectioni, since our idle process is 98%, but then it is not totally impossible either. Could you define the problem a little better, maybe the term "some time". You see I process 100's of millions of records and to me "some time" is anything after about 3 to 4

Also what is happening when you have the problems, are you running Windows, how is your drive space, memory, does it stop in places you modified recently, and stuff like that would be nice to know, otherwise, i'll need to get out my crystal ball and it's not been hitting a very good average recently.
