Subject [jira] [Commented] (AXIS-2698) SAX2EventRecorder causes Out of memory during Deserialization
Date Tue, 27 Oct 2015 07:23:27 GMT

    [ https://issues.apache.org/jira/browse/AXIS-2698?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14975873#comment-14975873

gaochao commented on AXIS-2698:
-------------------------------

I also meet the similar problem,
The thread org.apache.tomcat.util.threads.ThreadWithAttributes @ 0x4f068898 http-0.0.0.0-8080-Processor63
keeps local variables with total size 435,096,504 (46.12%) bytes.
The memory is accumulated in one instance of "org.apache.axis.encoding.DeserializationContext"
loaded by "org.jboss.mx.loading.UnifiedClassLoader3 @ 0x4cc718d8".

94M used by SAX2EventRecorder,  and there are also lots MessageElements, each size of them
is 472, maybe totally 2219524 entries.

>          Issue Type: Bug
>          Components: Serialization/Deserialization
>    Affects Versions: 1.2
>         Environment: IBM AIX 5.2.,  Client: java 1.4.2 Server: PERL, SOAPLite

> After undetermined time (3 or 4 days) the java client crashes with an out of memeory
exception. Analyzing the head dump showes that during the deserialization the SAX2EventRecorder$objArrayVector.add
 produces a huge amount of MessageElemets. The returned message is a 3times nested array containg
in the inner arry just a strings [ [ [ key~value, ..., key~value ] ] ]. Here a snippit of
the array
