Cisco Switch 100% CPU. Any way other than a reload?

I was checking on our config archive and issued "show archive" to a 4948 running 12.2(53)SG1 (It has been up for 10+ years, if it ain't broke....) Apparently there was a disconnect to the archive storage location and instead of listing the recent config archive filenames, it started regurgitating connection issues in an endless loop which I was unable to kill via the session. The line shows idle and is far past its timeout period, but due to the stuck process it isn't clearing itself. clear line, clear tcp tcb etc. all have no effect. Clear socket doesn't exist in this code base.

Is there any way to kill the following PID w/o having to reload the device?

show processes cpu sorted 5min CPU utilization for five seconds: 99%/0%; one minute: 99%; five minutes: 99% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process 202 4582100 250984 18256 86.38% 85.99% 86.24% 1 Virtual Exec 

Thanks in advance.
