Yesterday I updated to the latest expect port, 5.38.0_3, and since then I've had a lot of failures with spawned processes. My expect script spawns a telnet and then issues some commands. Every so often, the telnet goes into a spin loop, and expect times out on that command, yet the child expect keeps waiting for the process to begin. If I kill the looping telnet, expect gives me an error about a non-open file handle. It doens't happen every time, but it is happening with significant frequency. This has also happened with an expect script running the "host" program to see if a name resolves to test if the name server is up. Has anyone else run into this? My guess is it has something to do with TCL 8.4 since that's the only change from the prior version of expect (I compile without X on this server). Here's the script to check for an up name server: --cut here-- #!/usr/local/bin/expect -f # -*- tcl -*- # check if the name server is running on the given host. # return 0 if alive, 2 on timeout, 1 on any other error # V.
