Description From Tino Vázquez 2007-04-27 10:15:01

When the number of hosts exceeds a threshold (being set by the GridWay server
specs), the number of java process overloads the GridWay Server.

One possible solution would be to implement a mechanism to group this
monitoring processes (say, 5 in a row) instead of launching all of them
simultaneously.

A new IM MAD should be developed using a single (multi-threaded) Java process
to mitigate JVM start issues.
