10046 Level 8 Trace file disappeared

After playing around with this in development for a while I just tried setting Event 10046, Level 8 trace on a production process that was taking too long to run.  

Everything went smoothly, the trace file was being written to, when suddenly the trace file disappeared. The last time I checked it was a little over 2 Meg but I had max file size set to 2 Gig. All the space was freed up according to df -k.  

I tried setting the event to level 0 and back to level 8 but there was still no trace file. The session was still running.  

Here's what I ran:  

exec sys.dbms_system.set_bool_param_in_session(265, 16097,
'timed_statistics', true);

exec sys.dbms_system.set_int_param_in_session(265, 16097,
'max_dump_file_size', 2147483647);

exec sys.dbms_system.set_ev(265,16097,10046, 8, '');  

I'm on Oracle 8.1.7.2, Solaris 2.6.  

Does anyone have any ideas as to what might have happened to my file?    

Thanks,
