Hi all,
I am just wondering if you have seen this same issue. On one of our
servers, the rpcbind daemon used 3.6G memory; on another server, it
reported out of memory error:
svc_vc_create: makefd_xprt : out of memory
do_accept : out of memory
xdrrec_create: out of memory
svc_fd_xprtcopy: strdup failed
It seems lots of 16-byte buffers are allocated but never released. I am
still struggling to find where it is.
Just want to ask around.
Thanks,
