MemcachedConnection makes my zimbra server slowly

Postby hoanglv » Thu May 17, 2018 3:33 am

Hi,

after i blocked memcache by this guide

https://wiki.zimbra.com/wiki/Blocking_Memcached_Attack

i entered 2 commands:

su - zimbra
/opt/zimbra/bin/zmprov ms `zmhostname` zimbraMemcachedBindAddress 127.0.0.1
/opt/zimbra/bin/zmprov ms `zmhostname` zimbraMemcachedClientServerList 127.0.0.1

after that my zimbra server log said:

2018-05-17 10:06:40,568 WARN [Memcached IO over {MemcachedConnection to /127.0.0.1:11211}] [] MemcachedConnection - Closing, and reopening {QA sa=/127.0.0.1:11211, #Rops=0, #Wops=43949, #iq=0, topRop=null, topWop=net.spy.memcached.protocol.ascii.StoreOperationImpl@619a3efd, toWrite=0, interested=0}, attempt 8551.
