Cannot bind port

Running 5.3 on AIX 5.1 and, when running a TCL script from the command line (first line of the script calls the hcitcl interpreter: #!/qvdx/qdx5.3/integrator/bin/hcitcl), this error appears:

cannot bind port : Address already in use

Sometimes it fills up a screen until, finally, the script starts to run. I’ve also noticed it in a cron job that we run overnight.

There is no TCP communication; it’s a simple batch script that reads and writes to files.

Might this have something to do with whatever port the TCL interpreter is using, if it does, in fact, use a port???

Thanks for any help.
