At one of our sites we run a Novell Fileserver with some DOS Clients and a linux server. The linux server is running an older SuSE version with Linux 2.4.29 kernel, as well as various custom applications. It is running quiet stable so far without bigger problems. As we want to migrate our servers to Debian their is another system running Debian, a Linux 2.6.12 kernel build from debianized sources and the same custom applications as on the SuSE system. But for a reason, we can't figure out, the novell connection on that system fails in a random matter. It just "disappears" and logfiles (syslog and kern.log) state that the ncpfs connection is invalid. First we thought of a hardware problem, but that does not seem to be the reason, as we swapped the responsible NIC and the problem keeps happening. Then we thought it may be a kernel bug, which is maybe fixed in a newer version, upgraded the kernel, but the situation did not change. I thought one special application may be the point of failure, but it does run on the other host, too - without any problem. Anyways i straced the application to see whats happening when the connection breaks. Nothing, that could help. It's just normal operation until it gets into an "Input/Output Error" loop. At the current point i don't know what to do. I don't see possibilites to trace down the problem, nor can i find some hints via google or in this mailinglist so i want to ask if somebody can tell me how to trace down that problem, or give me some hints in any other way. The ncpfs software running on the server is 2.2.6, while the server without problems is running 2.2.0.18.
