Re: New warnings after upgrade: CompoundCachingTier - Error overflowing into lower caching tier - The element is too lar

Post by L. Mark Stone »

After making the change suggested by Zimbra Support and restarting mailboxd, I have no more CompoundCachingTier errors.

I've suggested to Zimbra Support that the default value for zimbraImapInactiveSessionEhcacheSize be increased to 100MB for new Zimbra installs.

Hope that helps others,
Mark

Hi Mark,

I'm seeing the same warnings in all mailbox.log files so I'll go the same route and raise zimbraImapInactiveSessionEhcacheSize to 100MB. I just wanted to let everyone know that zimbraImapInactiveSessionEhcacheSize can be set globally :

[zimbra@store ~]$ zmprov desc -a zimbraImapInactiveSessionEhcacheSize
zimbraImapInactiveSessionEhcacheSize
Ehcache: the maximum heap size of the inactive session cache in Bytes
before eviction. By default this value is 1 megabyte. This is a rough
limit,Due to internals of ehcache actual size in memory will often
exceed this limit by a modest margin.

type : long
value :
callback :
immutable : false
cardinality : single
requiredIn :
optionalIn : globalConfig,server,alwaysOnCluster
flags : serverInherited,serverPreferAlwaysOn
defaults : 1048576
min :
max :
id : 3004
requiresRestart : mailbox
since : 8.7.6

Hi,

So nice finding this post. Thank you very much! I'll apply this change to the servers experiencing this. Although as you said is benign, I rather not to have my logs so dirty with these messages.

I will also include this setting as default for all my deployments.

Thank you guys!
