the "select" poller cannot reliably use more than 1024 file descriptors on
some platforms. If your platform only supports select and reports "select
FAILED" on startup, you need to reduce maxconn until it works (slightly
below 500 in general). If this value is not set, it will default to the value
set in DEFAULT_MAXCONN at build time (reported in haproxy -vv) if no memory
limit is enforced, or will be computed based on the memory limit, the buffer
size, memory allocated to compression, SSL cache size, and use or not of SSL
and the associated maxsslconn (which can also be automatic).
below 500 in general). If this value is not set, it will automatically be
calculated based on the current file descriptors limit reported by the
"ulimit -n" command, possibly reduced to a lower value if a memory limit
is enforced, based on the buffer size, memory allocated to compression, SSL
cache size, and use or not of SSL and the associated maxsslconn (which can
