the current CVS version of umbrello seems to have a quite big memory problem.
It seems to be larger at the moment than before.
+ 2 GHZ Pentium IV
+ 512 MB RAM
+ 1036 MB SWAP ( total )
+ 1408 KB XMI file ( on disc )
+ top tells me:
- 1020(!!) MB virtual memory for umbrello
- 120 MB resident ( non swapped memory ) size
- 68 MB shared memory size
+ a lot of and very long swapping during load of
project ( several minutes )
+ kernel reaches out-of-memory state, if other apps
( konquerer, kmail, kdevelop ) are running
-> kernel kills umbrello during load
+ as soon as obviously unneeded data is swapped
away after load, I can restart other apps
( kmail, kdevelop, konqueror )
( obviously some memory is released after load )
+ smooth work ( including movement of
elements in diagrams ) is possible
+ swap memory is not significant increased during work
-> undo-memory seems to be NOT the source of problem
+ code generation is "de-activated" by selection of
language ADA -> no C++/JAVA code-generation part in XMI file
+ while project save during work is quite fast,
the total close of the project or normal termination of
umbrello isn't possible!
--> I have to kill umbrello after my last save action
Please tell me, if you need some more information.
But I can't provide the project file itself.
Other non important note:
+ change of operation signature is again possible
+ but false warn message is still activated with following
"Der von Ihnen gewählte Name wird bereits benutzt
Der Name wurde zurückgesetzt"
+ the change of the operation IS stored correct, after I click
the error-message away
