RE: Too many files open error on CVS/Linux

[Tom Gutschmidt]

I've seen this problem on other platforms as well. It might happen if cvs has lots of little changes to make all at once.

You can change the maximum number of open files on a Linux using the
following method:

echo 8192 > /proc/sys/fs/file-max

you should also set inode-max to 3 or 4 times file-max.

echo 32768 > /proc/sys/fs/inode-max

You can make these change permanent by editing /etc/sysctl.conf (RedHat
only I believe)
