Re: ndbmtd unexpected high memory usage

[Jonathan Lowsley]

I am using pmap to try to understand how the threads are consuming memory. I decreased transaction coordinator thread from 2 to 1 and see one of the allocations in pmap drop from 15961944 KB to 6999492 KB

these are from `pmap -x 5597|sort -nk2 `

tc={count=2,cpuset=6,7,14,15}
