5.2.3 ANSI GSS Sequence Could Cause Symbiont Crash

When using the ANSI GSS escape sequence with a parameter of zero, the ANSI

translator would crash and cause the print queue to stop. For example, the

sequence:

<CSI><SP>C

would cause DCPS to crash with the following error messages:

%%%%%%%%%%% OPCOM 3-DEC-1999 11:48:09.85 %%%%%%%%%%%

Message from user SYSTEM on RT495

Process SYMBIONT_49: %SYSTEM-F-INTDIV, arithmetic trap, integer divide by zero

5.2.4 Incorrectly Coded Font Causes Font Listings to Fail

When requesting a list of fonts from some printers, including the LN32 and

LNM40, the list would either not print or fail with a PostScript error. This

would occur if a DCPS ANSI print job had been printed on the printer since

the last time it was powered on. ANSI fonts created by DCPS have been ﬁxed

so that such font lists, including those produced using the printer’s console

and user-written PostScript programs that inquire about font information, now

succeed.

5.2.5 Layup Usage and Printer Errors Can Cause Memory Leaks

DCPS symbiont processes would sometimes use increasing amounts of memory

over time when you used layup ﬁles. This also occurred rarely for certain printer

error messages.

Also see Chapter 3 for information about a memory leak in OpenVMS Alpha

V7.1-2.
