Interval timer giving JBAS014143 error
I have an 30 second interval timer in my application which had been running for several weeks without incident. I have a log entry that indicates that the prior execution of this timer is still running. I have log entries that indicate that the timer action has completed within several milliseconds. When the timer fires, I spin off an asynchronous action(timerAction.jcmTimerAction) and then return:
@Timeout
@TransactionAttribute(TransactionAttributeType.NEVER)
public void timeoutHandler(Timer timer) {
LOGGER.debug("HA Timer Action Start");
timerAction.jcmTimerAction();
LOGGER.debug("HA Timer Action Done");
}
I see this in the log for the last timer that executes as expected.

I have subsequently rewritten this code to no longer use an interval timer, it instead creates a new single action timer each time the timer hander is invoked. I still would ,like to understand what might be happening here and if I am likely to see the same behavior with the new single action timer mechanism below.
@Timeout
@TransactionAttribute(TransactionAttributeType.NEVER)
public void timeoutHandler(Timer timer) {
long expiration = defaultExpiration;
if ((propertiesMap != null) && (propertiesMap.getInfo(PropertiesInfo.SYSTEM_PROPERTIES) != null)) {
expiration = propertiesMap.getInfo(PropertiesInfo.SYSTEM_PROPERTIES).getHaTimerInterval();
}
try {
timerAction.jcmTimerAction();
} catch(Exception e) {
// Eat any exception and restart timer
LOGGER.error("JCM timer action failure", e);
}
timerService.createSingleActionTimer(expiration, timerConfig);
}
