Re: kern/44625: memory exhaustion on NFS server while writing many files
I posted incorrect data.
The outputs from vmstat are unlikely; The statistics other than
Memory resource pool ones are not gathered in MONOLITHIC kernel.
Sorry for confusing.
I tried to vmstat -mW on MONOLITHIC kernel (see below), however,
output of vmstat is not much different from the one in orinal post.
The Npage of pnbufpl grows extremely.
I also tried some kernels checked out on other date. It seems that
this leakage is seen after struct componentname changes on Nov 30 2010.
regards,
