HA!  It turned out that my C program exits if can't it connect to my 
database after one try!  This is typical if the mysql deamon has not 
fully started.  I tried starting my "pollster" daemon right after the 
mysql daemon -- to resolve this, I placed a loop in my C program that 
delays and retries to connect to the mysql database until it succeeds 
within a certain number of tries.

BTW, syslog is disabled by default on the TS-7800 in order to reduce 
wear on the flash memory.  I didn't know that.  So for everyone who 
wants to collect data in the syslog, copy syslog.conf-debian to 
syslog.conf in the /etc directory.  Just make sure you keep a copy of 
the old syslog.conf just in case you want to disable syslog again.

Thanks for your help fellas!
