I've been wrestling with this problem for a little while.
Environment: JBoss 3.2.3, Sun JDK 1.4.2_01 on linux (debian)
I have a stateful bean which appears to work fine for the most part.
I can generally do some operations on it, within a transaction, and then remove the bean. I've set the passivation time very low (20 secs) as well as the expiry times on the bean as below:
<remover-period>10</remover-period>
<overager-period>10</overager-period>
<max-bean-life>60</max-bean-life>
<max-bean-age>20</max-bean-age>I've found one case however, where this can cause a problem. If I get a handle from the stateful bean, in order to use it ( possibly to put in an HTTPSession, or someother) that works fine.
Restoring the bean (and possibly activating it) from the container also works fine. HOWEVER, I have found that if the remote stub does that, OUTSIDE of a transaction context, there is a ref lock left on the stateful session bean, and from there it won't passivate properly - is this proper behaviour?? (BTW, I haven't yet tried this within a UserTransaction).
Lots of warning like this:
15:20:32,559 WARN [AbstractInstanceCache] Unable to passivate due to ctx lock, id=dpsp9lca-7
15:20:52,597 WARN [AbstractInstanceCache] Unable to passivate due to ctx lock, id=dpsp9lca-7
15:21:12,639 WARN [AbstractInstanceCache] Unable to passivate due to ctx lock, id=dpsp9lca-7
There's some more detail in the snippet of log attached.
