The infinite-recursing code as originally written should work, because catch is supposed to catch errors. And if you run tclsh and try the code, it does the right thing, which is to generate a tcl exception when the recursion goes too deep (which is 1000 levels by default). The problem is really a configuration bug in AOLserver, where the default stacksize is not enough to accomodate the max size of the tcl stack. Two possible fixes: set the default tcl recursion limit lower, or patch the code so that TclpCheckStackSpace() calls NsTclCheckStackSpace(), which is there for exactly this problem. This is done in in the tcl7.6 core, but not 8.x as its just the basic tcl distrib unpatched. -J
