They happen only on heavily-loaded | machines; soft limits in the kernel are being exceeded. | | These two lines added to rc.sysinit or rc.local should solve your | problem: | echo "4096" > /proc/sys/kernel/file-max | echo "12288" > /proc/sys/kernel/inode-max | If they don't, make them larger. Just keep inode-max three times as | large as file-max (suggested by a kernel source code comment...) | | You might also want to do this if you ever get "out of memory" | messages from device drivers: | echo 300 400 500 > /proc/sys/vm/freepages | We use that line on machines with very heavy network traffic. | | michaelkjohnson
In /usr/src/linux/include/linux/tasks.h :
change #define NR_TASKS 256 to #define NR_TASKS 1024 since #define MAX_TASKS_PER_USER (NR_TASKS/2)
