[-- Attachment #1 --] Hello, I went to open up a new shell to our login server (recently rebuilt from Debian to FreeBSD) and found problems allocating a new pty. With a 256-pty limit, I'm surprised more people haven't had this problem. With team of 8 SysAdmins, each leaving about 30 windows open in screen sessions, 256 starts feeling a bit claustrophobic. I found a questions thread from January 2006 and these PRs: standards/90896: not enough PTYs in the FreeBSD kern/25866: [patch] more than 256 ptys, up to 1302 ptys. The latter appears to have been kicking around since FreeBSD 4.3 (still open). What can I do to help get that limit raised? Does anyone have a patch against 6.2? If not, would anyone be interested in writing one?
