In 2.2.x NR_TASKS is set in stone during compile time. If you need more simultaneous tasks you must recompile with NR_TASKS set higher. You can set it as high as 4090 or so (read the docs). In 2.4.x it can be set via proc at runtime. Again, uptime means absolutely nothing. -- Mike A. Harris - Linux advocate - Free Software advocate This message is copyright 2001, all rights reserved.

increasing the 512 process limit at run-time?
I note that include/linux/tasks.h contains #define NR_TASKS 512 Can I tune this at run-time? My lovely server's been up since the day 2.2.16 was released, and now having hit the limit I don't want to reboot :) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
