[jboss-jira] [JBoss JIRA] (WFLY-7457) UT005013 causes OutOfMemoryError

    [ https://issues.jboss.org/browse/WFLY-7457?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13319208#comment-13319208 ] 

Stuart Douglas commented on WFLY-7457:
--------------------------------------

Can you provide more details?

Judging by your description I think you are saying that a SSL connection that is simply dropped instead of being closed cleanly is causing out of memory errors?

If so can you provide the 'jmap -histo' output from the JVM to give details about exactly what is running out of memory?

> There's some F5 WAF within the network where our WildFly is running. The WAF sends multiple Keep Alive-Requests to our WAF via TCP, but without sending "close_notify" after the communication has ended. 
> Undertow throws UT005013, which is correct, but this causes the JVM to run out of Memory. The keepalive is sent 12 times per minute (every 5 seconds) to our WildFly.
> We already installed an update of Undertow (1.4.3); This didn't help.
