What is the real meaning of ERRpipebusy?

[Eric Boehm]

I am seeing the following errors in my samba logs.

I am trying to figure out if this is a problem with Samba or with the NT
domain. I searched the mail archives at http://marc.theaimsgroup.com/. All I
turned up was a previous problem with long user lists that was fixed.

The share in question (export) contains ClearCase VOBs. The user experiences
the problems if he tries to mount all the VOBs at once. He doesn't have any
problems if he tries to mount them one at a time. There are 28 VOBs contained
in this share.

I am running Samba 2.0.7 on Solaris 7. My smb.conf is:
