Hi!
I also have a problem with PAM4.0 SP1 performance.
First of all, my first login of the day takes more than 5min, and I think that this could be related with EEM.
Second, some times the processes takes some time to start and some time to execute, my log files are full of warnings and error the most of them telling me this:
2012-10-12 10:14:12,146 WARN [com.arjuna.ats.jta.logging.loggerI18N] [ Thread-12] [com.arjuna.ats.internal.jta.resources.arjunacore.norecoveryxa] [com.arjuna.ats.internal.jta.resources.arjunacore.norecoveryxa] Could not find new XAResource to use for recovering non-serializable XAResource < 131075, 30, 28, 48459755101545310056581005548555852102102535349485458974954101544897551015453100565810055485558521021025353494854589749541015499 >
I think that XA Transaction are correctly configured.
