| It's been 24 hours and the answer to this question is yes.  I initiated a 
| connection yesterday morning and let it sit.  This morning I attempted 
| another sp_who command and it failed.
| 
| This led us to a message in a server log that confirmed what a lot of us 
| thought right away.   They were killing the processes.  I suspect that the 
| current owners of the system do not even know they are doing it.  Ugh!
| 
| We found the process that was doing the killing and there were multiple 
| scenarios of why a process would be killed.  The one that got the TSQL 
| process was a check in the sysprocesses table for any hostprocess name 
| that was not 8 characters in length.  If such a process was up for more 
| than 24 hours, it was killed.  It appears that the processes from the 
| Sybase client on the VAX using the SRI INET driver seems to always produce 
| 8 character hostprocess names.  The connection from TSQL is less than 8 
| characters, thus it was killed after 24 hours.
| 
| I want to thank all that helped find this issue and apologize for 
| something that, in retrospect, should have been correctable internally.  I 
| did find out that not only is the price for FreeTDS right, the support is 
| superb.

I hope that they are paying you a lot of money to work there!
