TCL FTP package

[Richard Hart]

Hi All.

Just an FYI.

We have (hopefully!) just fixed an issue that’s been going on for some time.

We use a UPoC with the FTP package to grab appropriate files from a server and place them into another directory for further processing by Cloverleaf.

Every so often we had a crash (see example logs below).  Since no data was lost, there was little priority to fix this. After a recent ‘upgrade’, the number of crashes became unacceptable and we investigated further.

A change of timeout value lessened the number of timeouts, but a change from active to passive ensured that Cloverleaf recovered from the timeout.

The exit_log:

Terminated by signal 0, core dumped at Fri Mar 12 04:10:07 2010

The site log file:
