That error string doesn't show up anywhere in the Performer libraries;
it must be someplace in Viewkit, or perhaps in a loader.
As for the overall problem, it sounds as if there's a memory leak, your
application is growing over the hour and eventually runs out of memory.
If it were the Performer arena that ran out, you'd get the usual
"Unable to allocate %d bytes from arena" message rather than the above.
Traditional debugging techniques are probably your best bet here. If
the program exits after printing the above message, try loading it into
the debugger (dbx or cvd) and set a breakpoint in exit. Let it run, and
once it reaches the breakpoint type 'where' to get a stack trace. This
will show exactly where the message is coming from.
