I am trying to debug some core dump problems. I should be able to run
imap by itself right? How to fix?
imap(root): Fatal: setgroups() failed: Too many extra groups
I am using latest nightly code.
That error indicates that the root account is a member of too many
groups to use the setgroups() system call, at least after Dovecot
adds its mail_extra_groups list. Typically systems control that limit
with the NGROUPS_MAX or kern.ngroups kernel parameter (depending on
the heritage of the specific OS) and the traditional limit is 16,
with some systems defaulting to 32. Some systems are held to 32 as an
Some programs deal with that limit by truncating the list of groups
provided to setgroups() but that can be a tricky business.
