Re: help increase process/kernel memory please

Hi,

I clearly have a problem figuring out how to increase the limits for memory available to a process and the kernel.

I'm running a Perl app that need lots of memory and I would like to make around 2G available to it, the box has 4G physical RAM.

Which knob(s) should be tweaked? System is running 6-STABLE from around 1st of October.

This is what I see when the process exits:
Out of memory during "large" request for 528384 bytes, total sbrk() is 536416256 bytes

I'm depending on a solution to this and would be a really happy person if someone could please guide me.

Per olof

You should try setting kern.maxdsize in /boot/loader.conf and then reboot the system. This sysctl sets the maximum data size of a running process you may also have to tune some of the limits using ulimit. The example below sets the max data size to 1.5Gb:

kern.maxdsiz="1610612736"
