Thanks for the information Scott!
We are currently using ECF 3.12 (from Mars release), so I will give
the new version a try.
Bye, Peter

Hi Peter,
This was a bug having to do with the use of the class
resolver....never calling ServiceTracker.close. I can't
remember the bug right now but I will look it up later and reply
to this email. In any event, it has been fixed in more recent
versions. Which version are you on?
Thanks,
Scott

Hi all,
recently I had an OutOfMemory on one of our app servers which
is connected to some 150 rcp clients via ecf.
In the memory dump (1GB heap) I recognized about 437000
ServiceTracker instances which, from my point of view, seems
too many.
Local testing with a profiler showed, that the application
server creates 11 instances of ServiceTracker for each client
"connect". After closing the Client these instances stay there
- they do not seem to get closed / garbage collected.
In Production the application server is running for a long
time and clients come and go the whole day so this could sum
up.
Please see below for the stacktraces of the ServiceTracker
creation when one client connects.
Thanks for any hints or thoughts about this problem.
Best regards, Peter
PS: our setup
* we use the generic provider
* server exports / client imports 3 remote services
