remsh does not work when more than 200 processes are started

[Dilipraj]

Hi,
We are trying to execute remote processes on Sequent machine by remshell from HP-UX machine. At a time probably around 400 processes starts from HP-UX and tries to do remsh to get connect on sequent. But it looks like there is a limit on number of remsh doing the work. After 200 processes, the followon processes just stop responding on remsh and i keep getting ' TCP: t_rrcmd: can't connect to: .....' error. Anybody knows whats the limit on simultaneous processes with remsh ?. Is there any way to increase its capabilities ? . I am new to unix, don't know much abt remsh .. would like to explore more . Any help is appreciated..
Thanks

output of /usr/sbin/kmtune is??

look at maxusers, nfiles, nproc, ...

Hi,

it's been a long time since I did work on a Sequent, so I may be wrong with some details:
- check for the kernel parameters MAXFILES, MAXUPRC, NFILES, NPROC (like Harry told you) the command would be "idtune", IIRC
- check for enough existing and available pseudo tty files

Just my $0.02,
Wodisch

probably maxuprc kernel parm

Besides the suggestions above, it could be the Sequent machine running out of memory too.
