Here's the deal
I'm load-testing my application; Orion's behaving properly and fast while
the load doesn't get too high... but when it happens (say, 50
requests/second of dynamic pages),
DeadLock's start to ocurr....
Fine by me, I'm not ready to sacrifice data consistency to elevate the
performance, BUT
Somehow, Orion, after these problems start to ocurr, doesn't free the
DataBase Connections it allocated (as you can see in the application log I'm
attaching, first there are
DeadLocks, then the server starts to fail waiting for connections). When I
shut down the server, it starts printing in stdout:
Datasource not closed, check out your code!
Funny thing, I checked my code and guess what... no jdbc code at all.....
;-) I'm using CMP
This thing with variants happens when using different drivers aimed at
different DBs:
jConnect/Sybase
OracleDriver/Oracle
HSQL/HSQL
SprintA2000/SQL 7
My guess is that when a request or response is cancelled by the requester,
orion (perhaps OrionPooledDataSource) doesn't rollback the transactions nor
it frees the connections
The result being my orionserver coming to a complete halt whenever the
requests are above a certain number, and sometimes it even refuses to shut
down
This has me VERY worried because of possible DoS attacks, or even peaks in
the site's use, which will ultimately be solved only by somebody pushing the
reset button...
Anybody has stumbled across this before?
Orion Team, comments?
