RAC session blocked in wait "SQL*Net message from dblink"

Hi everybody,

I have got two database:
* a Oracle RAC3 "Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production" with 3 nodes on AIX machines.
* a Oracle9i Enterprise Edition Release 9.2.0.8.0 - 64bit Production) with a single node.

I have a procedure installed on the RAC3, that i'll call prc_A, it calls another procedure, that i'll call prc_b, through dblink in a single node db. When the latter procedure "prc_b" employes more time (about 60 minutes) to terminate the own execution, the session, on the Oracle RAC3, remains blocked in waiting with ACTIVE state and "SQL*Net message from dblink" event. So when prc_B complete the own execution, the session of RAC3 is always blocked until it's not killed.

Howdy, Stranger!
