XI Error JCO_SYSTEM_FAILURE.MAPPING: Queue stopped

In SMQ2, i can see a queue stuck giving error:

XI Error JCO_SYSTEM_FAILURE.MAPPING: Queue stopped

when i click it...it leads me to a SXMB_MONI entry..

which corresponds to a IDOC to File scenario, where a message mapping fails giving the following error,

<SAP:Category>XIServer</SAP:Category>

<SAP:Code area="MAPPING">JCO_SYSTEM_FAILURE</SAP:Code>

<SAP:P1>java.lang.OutOfMemoryError</SAP:P1>

<SAP:Stack>&quot;SYSTEM FAILURE&quot; during JCo call. java.lang.OutOfMemoryError</SAP:Stack>

<SAP:Retry>A</SAP:Retry>

If i try to reEXECUTE the LUW from SMQ2, it again shows the error.......

how can i solve the problem without delecting the queue

hi ,

This error is coming because your message is very large or lots of large xsd files are uploaded in XI

you need to increase the memory used by JVM for your XI. How to increase the Memory ? for answer go to this blog.
