[jira] [Commented] (MINIFICPP-1847) Investigate high memory usage scenarios

    [ https://issues.apache.org/jira/browse/MINIFICPP-1847?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17541484#comment-17541484 ] 

Marton Szasz commented on MINIFICPP-1847:
-----------------------------------------

I could get GBs of memory usage with a high volume (5000 msg/sec) ListenSyslog. Ideally it should always stay below 100 MB, except if the messages are large. I was testing with short syslog messages, maybe 100 bytes each. Even if a lot of them a queued in memory, they should take up that much space.

> Connections are limited to 10 MB by default IIRC, but we should make sure that this is enforced.
