DNSE-301 — Sockets table is exhausted
Function socket() returned file descriptor with number higher than allowed maximum. List of pending requests follows this message (if W-level messages are allowed).
Proxy reaction depends on the kind of the unsatisfied request:
UDP request is replied with ServFail response code
TCP connection is closed
internal request fails and causes failure recovery of the originator.
If the requests table is filled by a reasonable amount of requests in reasonable state, increase size of the sockets table in the configuration (item sockets-table-size).
