ProCurve 2620 Config-catch File empty

[Chris_Jo]

Dear colleagues,

we are operating aprox. 600 Procurve 2620 switches.

I use a perl script to connect via telnet and send a command to put the running.-config to a file on a tftp-server.

About 40 of this files are empty, all others are fine. They are working all on newest firmware and i already compared two running-configs at a working put and a non-working put, but found no differences except the IP and Hostnames. I also tried to get the startup-config, same problem.

Does anyone have an Idea?

THX a lot for your suggestions
