I'm having a terrible time with memory leaks in my apps.
I'm running WebObjects 5.2.1 with Java 1.4.1 and MySQL 3.23.53.
Developing on a dual G4 running Mac OS X 10.2.6.
Deploying on XServes (one for apps, one for DB).
I'm working on a mission critical project to import records into our
DB, but finding that my WebObjects apps are getting (exponentially?)
slower and flakier with the size of the DB. We're only talking about
150k records (33.5 MB) so far, distributed primarily across 5 or 6
tables. The query times are still great outside of WebObjects (for
example, via phpmyadmin).
I've confirmed via Process Viewer that the java process is balooning
out of control. Incidently, the browser (Safari usually, sometimes
Explorer) also balloons out of control eventually as well.
What gives? Any ideas? Known bugs?
Things I've tried:
- increasing the memory for the app. No change.
- forcing garbage collection. No change.
- emptying the editing context. No change.
- scaling back to java 1.3.1. No change.
- redeploying old pre-troubles version. Same problems.
- indexing a bunch of critical DB fields. Helped a lot with speed.
Doesn't stop the leak.
- deleting the new imported records. Works great! 8 |
I'd love to pay good money to a WebObjects developer in the Seattle
area who'd like to help get this figured out ASAP.
Many thanks,
Robert Head
