Hi all,

I'm using Dovecot version 2.3.21 on an up to date Void Linux on a 6 core 12 thread Ryzen with 48GB RAM, 1TB NVMe, and 12TB of 7200 RPM spinning rust hard drives.

Recently I've been getting the dreaded X error "Maximum number of clients exceeded", so I performed an lsof -U to find who was using UNIX sockets. This uncovered a buggy looping program I wrote using up gobs of UNIX sockets, along with some browsers, dbus-daemon, electron (used by vscode), smbd, and Dovecot, which uses 36 UNIX sockets.

I can kill dbus-daemon and the buggy program I wrote, minimize use of browsers, disable smbd except when I (rarely) need it, but can you think of things I can do to reduce the number of UNIX sockets used by Dovecot on my machine?

Thanks,

SteveT
