Just a quick note that may help somebody out... I upgraded my 5.0_STABLE amd64 box to 6.0_STABLE this weekend and found that dovecot (2.1.10 from pkgsrc) would not accept imap connections -- it was dying with the following: Oct 21 16:25:38 imap-login: Error: Cannot map anonymous memoryCannot allocate memory: Cannot allocate memory Oct 21 16:25:38 imap-login: Fatal: master: service(imap-login): child 15079 returned error 1 After much googling, poking of configuration files etc. I found that I could get dovecot to run by increasing the vsz_limit from 128M to 256M! The default value is 64M but I had to raise it to 128M back when I moved from version 1.13 to 1.14 (under 5.0_STABLE). Now, with the new 6.0_STABLE I had to bump it up again -- this time to 256M! Any idea why NetBSD requires so much more memory than the dovecot default? thanks, Steve
