*SOLVED* Unable to fork: Cannot allocate memory [message #9094]

When I attempt to vzctl enter ###, I get the error "Unable to fork: Cannot allocate memory"

I ran a top and I'm not maxing out memory and nothing in swap is being used.

Any ideas?

cat /proc/user_beancounters

paste it here and we will show you which resource is being exhausted. read the UBC page in the wiki in the meantime.

In your UBC, kmemsize has failcnts for veid 1200. To raise this metric limit:

vzctl set 1200 --kmemsize 12752512:12752512 --save; vzctl restart 1200

Basically, your resource limits are too low for your applications' demands. This will fix that, at least on this resource, kernel memory.

Hope this helps.

Interesting -- that was the VPS I was trying to get into which gave me that error.

I find it weird that it ran out of memory, it should have 128 of memory and up to a gig of burst and there's nothing but a small postfix server running on it.

Very odd.

Thanks though
