No the mail server is ok (it's sendmail) and it is clearly a problem with
linux's filesystem.

This existed in the 2.0 kernels and is still here in 2.2. I think this comes
in a general attitude of the linux developers: "this is not a normal

I'm not sure it is considered as bugs by the linux community, at last the
filesystem problem is not, for sure.

Hardware: I buy hardware for applications. For a critical system I wouldn't
chose the OS because a ethernet or SCSI board is not supported by NetBSD,
I would just buy another one.
Software: if it's really needed and only available for linux of course I would
install a linux system for it, but this should be really marginal (I don't know
of a program available only for linux). For the average commercial soft
I'd use solaris instead.

Mee to ! My dataless workstations are running linux (because of staroffice,
and a few other things). If one goes bad I just reinstall it: I have
kickstart set up, I just need to put the floppy in, hit reset, wait for the
kernel to load and remove the floppy. 1/2 hour after it's back up and running.
Clearly this is not acceptable for a server.

PS: another thing I forgot to add: my linux clients have problems with the
solaris NFS server, sometime they just hang, sometime the local cache gets
corrupt. The ethernet driver is a bit flacky for these boards (SMC) but
this shoudl't prevent NFS from recovering.
