当我使用Java MemcachedClient(com.whalin.MemCached(设置大量数据时，出现broken pipe和Connection reset by peer错误。
这是我的配置文件。[/etc/memcached.conf]
# memcached default config file
# 2003 - Jay Bonci <jaybonci@debian.org>
# This configuration file is read by the start-memcached script provided as
# part of the Debian GNU/Linux distribution.
# Run memcached as a daemon. This command is implied, and is not needed for the
# daemon to run. See the README.Debian that comes with this package for more
# information.
-d
# Log memcached's output to /var/log/memcached
logfile /var/log/memcached.log
# Be verbose
-v
# Be even more verbose (print client commands as well)
-vv
# Start with a cap of 64 megs of memory. It's reasonable, and the daemon default
# Note that the daemon will grow to this size, but does not start out holding this much
# memory
-m 4096
# Default connection port is 11211
-p 11311
# Run the daemon as root. The start-memcached will default to running as root if no
# -u command is present in this config file
-u memcache
# Specify which IP address to listen on. The default is to listen on all IP addresses
# This parameter is one of the only security measures that memcached has, so make sure
# it's listening on a firewalled interface.
-l 127.0.0.1
# Limit the number of simultaneous incoming connections. The daemon default is 1024
# -c 1024
# Lock down all paged memory. Consult with the README and homepage before you do this
# -k
# Return error when memory is exhausted (rather than removing items)
# -M
# Maximize core file limit
# -r
即使大小增加到 4096，这些错误仍然会出现。
还有一个问题： 无法获取日志文件，即使它是未注释的
运行进程
memcache 9304 1 0 11:26 ? 00:00:00 /usr/bin/memcached -v -vv -m 4096 -p 11311 -u memcache -l 127.0.0.1
仅供参考：从数据库读取 50000 条记录，添加到地图并将该地图存储到 Memcache 中。

我认为问题可能是您正在尝试将非常大的对象存储到 memcache 中
默认情况下，memcache 允许设置最大 1MB 的对象。在较新版本的 memcache 中，您可以设置 -I 选项以将大小增加到最大 128MB。(https://linux.die.net/man/1/memcached(
不过我不会推荐它。最好创建较小的对象。
