We (Rob Banz and I) are seeing the same thing on Solaris 10 x86. We
started our mass mail migration this past monday and a number of user
migrations have failed due to the same error.
We haven't found the cause yet, but to get around it for now we
cranked up the per-process FD limit and limited the number of
requests a imapd is allowed to handle. It looks like a file
descriptor leak of some sort. So far that has been a decent work-around.
