One possibility might be running out of pseudo-terminals to support the login sessions. pty's are created as needed I think, and the code that handles it is in sys/kern/tty_pty.c. The limits on it appear to be 256 ptys: /* * This function creates and initializes a pts/ptc pair * * pts == /dev/tty[pqrsPQRS][0123456789abcdefghijklmnopqrstuv] * ptc == /dev/pty[pqrsPQRS][0123456789abcdefghijklmnopqrstuv] * * XXX: define and add mapping of upper minor bits to allow more * than 256 ptys. */ I don't know if simply changing the : static char *names = "pqrsPQRS"; to something longer is all that would be required or if there are other factors involved. -- Ken Smith - From there to here, from here to | kensmith_at_cse.buffalo.edu there, funny things are everywhere. | - Theodore Geisel |Received on Thu Nov 20 2003 - 07:41:17 UTC
