    Application deadlock detected in JBoss 3.2.2RC3

    Rafal Kedziorski Novice

      Hi,

      since we use JBoss 3.2.2RC3 we get sometimes:

      10:41:06,561 WARN [TxInterceptorCMT] Application deadlock detected retrying 1
      11:17:25,338 WARN [TxInterceptorCMT] Application deadlock detected retrying 1
      11:17:25,385 WARN [TxInterceptorCMT] Application deadlock detected retrying 1

      11:17:25,588 WARN [TxInterceptorCMT] Application deadlock detected retrying 2

      and there one TRACE

      Our client is sending an Request thru HTTP to an Servlet, which is calling an special stateless session bean facade (transaction is set to Required). This session bean check some permissions and the data, than is calling other stateless session bean facade with the given business logic (transaction is set to Required). The business logic uses entity beans (transaction for the entity beans is set to Mandatory and all get methods are read-only).

      Is this an knowing problem in RC3?
