Error in Xemacs

Hello Team, I am Ramesh,System Administrator at Philips Software Center Bangalore India. I have installed Xemacs on one of the Sun box running solaris 8. My end users are complaining that Xemacs hangs sometimes and following is the error messages (which is in blue) it gives. Is it because of not enough memory available during editing or is it some other problem? Please let me know. Memory exhausted Fatal error: assertion failed, file eval.c, line 1877, abort() Fatal error (6). Your files have been auto-saved. Use `M-x recover-session' to recover them. If you have access to the PROBLEMS file that came with your version of XEmacs, please check to see if your crash is described there, as there may be a workaround available. Otherwise, please report this bug by running the send-pr script included with XEmacs, or selecting `Send Bug Report' from the help menu. As a last resort send ordinary email to `crashes(a)xemacs.org'. *MAKE SURE* to include the information in the command M-x describe-installation. If at all possible, *please* try to obtain a C stack backtrace; it will help us immensely in determining what went wrong. To do this, locate the core file that was produced as a result of this crash (it's usually called `core' and is located in the directory in which you started the editor, or maybe in your home directory), and type gdb /opt/sfw/bin/xemacs core then type `where' when the debugger prompt comes up. (If you don't have GDB on your system, you might have DBX, or XDB, or SDB. A similar procedure should work for all of these.
