1. After successfully compiling the same code about 20 times the compiler decides it has insufficient memory to do another compile.
This is a large 100%IDL/CORBA/Visibroker-ORB/100%Java project of about 40000 lines of code/300 classes. Its a distributed
client-server application that functions as the backbone for a major artificial intelligence information highway with OO database
and CORBA CosNaming and CosTransaction service interfaces.

We compile using visibrokers (idl2java and vbjc compilers) and Poet's ptjavac compiler. vbjc and ptjavac wrapper javac so its
impossible for us to determine where the memory leak is. We never have any runtime problems, only compile time problems.
Most of the time we don't get any messages from the operating system - I run a visibroker NameService tool called osfind and i
ts unusual lack of information is just sufficient to let me know our network connections are hosed and a system reboot is required
to clear the problem. Currently this is happening to us about twice-a-day when our compiler workload is heavy.

On occassion the compiler does sneak in a message such as the following before the system quits in the middle of a compile
complains about low memory. The message follows:

***end pasted message***

The error message above is meaningless as it is something different every time we capture it. Seems to just depend on where in the
compilation process we are when the low memory message is issued.

We are always able to close everything down each time it occurs but any attempt to do anything, bring up a browser, open
notepad, etc. results in the low memory warning - unable to complete the request; and it doesn't matter if I just shutdown several
apps releasing more memory than the new request requires. The operating system is unable to recover without a reboot.

I believe its either a compiler memory leak or a network connection (possibly network resource) related issue.
Appreciate any ideas you can give us to help troubleshoot, thanks.

Installed cloudscape from www.cloudscape.com,
ran cloudview (lots of Swing GUI components).
Menus in the menubar worked normally for a few
minutes and a few invocations, then stopped working;
after that, clicking on a menu item would highlight
the word, but the menu would not drop down.
