We've cranked it up to 800 on a -current system to accomodate some honkin' big apache processes we've got running. I know people that've increased it to 1,000 on -Stable. The default is 200, so try increasing it by steps of 200 until you no longer see that error. Increasing it to a larger value than needed will just waste precious kernel memory address space.
