This one is really strange and I just don't find where Virtualmin was configuring this earlier and not now anymore... :
On a virtualmin Pro installation that we installed a year ago, we have a comfortable setting:cat /proc/sys/fs/file-max
But on new installs made a few weeks back we had this:cat /proc/sys/fs/file-max
Rather very insufficient open files maximum (taking in account mysql open files requirements for smoothly running cached databases)...
We have manually set it higher after last boot, but still don't find where Virtualmin did set that value earlier, and why it's so small (maybe default Ubuntu value) now ?
Any hints on what's virtualmin's recommended way to fix this issue so that the value is higher (even dynamically computed with available memory as seems to be the case on older installs, but with same 8.04LTS up-to-date release) would be welcome :-) ?
Also looks like there is a bug in virtualmin Pro setup that doesn't raise that value ;-) ?
