Looking in the logs I see: 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. /dale -- Dale Ghent Specialist, Storage and UNIX Systems UMBC - Office of Information Technology ECS 201 - x51705 ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
