This is a bit strange - I seem to be getting a Deque Full error when I
try and close a connection. It doesn't happen all the time, and I only
just saw it for the first time a few days ago (in production...), and
bouncing Geronimo (stop/start) seemed to fix it. I can understand why
it might happen when I try to get a connection, but it shouldn't be
happening when I try and close one, surely? Doesn't seem terribly
logical.
Anyway, this occurred on Geronimo 1.1.1 while connected to a DB2
database, and the stack trace follows. I've replaced the names of the
classes we've written my MYCLASS_*, just to be on the safe side with
regards to confidentiality policies and whatnot.
My initial thought is that it's maybe a threading issue? If Thread A
tries to close a connection, but gets interrupted part-way through by
Thread B, which creates a connection, is that a potential way for this
to happen? Also, is it likely to have been fixed in a later version
of Geronimo? Given how much trouble I've had finding
"SinglePoolConnectionInterceptor", I'd say it's at least moved
somewhere else...
Anyway, I've been told to find an answer today, and I guess I'm just
posting this in the hope that I'll get lucky and someone will answer
:).
Thanks all,
