Hi All, Has there been any activity to resolve this problem. This is a big show-stopper for us. It only takes a few minutes with a handful of users before we run out of memory. If we can't get a resolution fairly soon, we might be forced to abandon OJB (even though I think it's a great product).

In OJB test suite shipped with a test called MetadataMultithreadedTest. This test use the 'pre thread metadata changes' feature. I modified the test and repeat the test 60 times and check the free memory of the JVM. All seems ok - using JVM 1.4.1_05-b01 Test results: RuntimeMetadataChanges test take: 31135 ms Free Memory before test: 125MB Free Memory after test: 92MB (JVM gc seems work correct and free memory) Free Memory after test after gc: 123MB regards, Armin > Roger Janssen > > > -----Original Message----- > From: Jason Pyeron [mailto:[EMAIL PROTECTED] > Sent: maandag 17 november 2003 15:06 > To: OJB Users List > Subject: Re: [rc4 / BUG] major memory leak in MetadataManager > > > On Mon, 17 Nov 2003, Janssen, Roger wrote: > > >>can anybody confirm this, is anybody working on this? > > > are you using ojb from CVS or download? > > I will test it from CVS later on, hopefully today. > > >>for me this is a showstopper, which is kind of a problem because it >>occurs in a live hosted webapp. > > > if true, then DITO. > > -Jason Pyeron > > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
