Hm, maybe you have set EPICS_CA_AUTO_ADDR_LIST or EPICS_CA_ADDR_LIST in your 
interactive shell environment? Note that cron (necessarily) starts its jobs 
with a fresh (and non-interactive) environment under a /bin/sh. It could be 
/bin/sh is not bash, but a simpler shell like dash (this is the case with 
newer versions of ubuntu, for instance). Thus /bin/sh might not read 
~/.bashrc. It _does_ read ~/.profile if it exists, though.
