transaction roll back & jvm's being thrown out of cluster

managed servers are getting thrown out of cluster

recieved the below error messages

<BEA-010026> <Exception occurred during commit of transaction
Caused by: weblogic.transaction.internal.TimedOutException: Transaction has timed out when making request to XAResource


<BEA-000144> <Managed server WLS1D has been suspended or shutdown.>

I see that many transactions are being rolled back and those exceptions are causing the memory to get filled frequently, and so the garbage collection takes time causing the multicast messages to miss.
change the value of your JTA in config.xml and restart to check if we still get the same problems.

stop the domain
take backup of config.xml
change  <jta>
<timeout-seconds>90</timeout-seconds>
<security-interop-mode>default</security-interop-mode>
</jta>

from 90 to 600 and start the servers.
Fixed
