Hello Mark,<br>
<br>
Can you share with us the WARN or ERROR messages that had you
contact Zimbra support initially ? So we can check if we're also
facing Ehcache issues on our ZCS infrastructures?<br>
<br>
Regards,<br>
Frédéric.<br>

<div dir="ltr">Hello again<br>
<br>
Security apart the article lets suppose a <i>zimbraMemcachedClientServerList</i>
empty attribute is always safer, but IMAP performance could
be better with it because the zimbra store would use the
memcached service for IMAP protocol instead of EhCache.</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">The official Zimbra guide says :<br>
zimbraMemcachedClientServerList : list of host:port for
memcached servers;<b> set to empty value to disable the use
of memcached
</b></div>
<div dir="ltr"><br>
</div>
<div dir="ltr">I also have an empty attribute on my Zimbra
8.8.8 multi-store environment. If I have I/O performance
issues on my zimbra stores, should I set the
zimbraMemcachedClientServerList server attribute or let it
empty ?<br>
</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">Why does the memcached service is better than
EhCache which is memory based ?<br>

<br>
I might be wrong.<br>
But considereing there are attributed CVE numbers and
patches, it looks to me as standard procedure:<br>
. vulnerability discovered and embargoed<br>
. software company contacted<br>
. software company acknowledged the vulnerability<br>
. software company issued patch<br>
. a couple days later, vulnerability went public with
explanations<br>
