Hi all,
I have a general memory usage question regarding GNUstep applications.
My app allows users to fetch objects from a database. The fetched raw
data is converted to Objective-C objects in memory. These objects are
held in a dic. As the user continues to do fetches the memory usages of
the process goes up:
prstat
PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP
27357 paravici 423M 414M sleep 59 0 0:36:36 0.6% SmartClient/1
...
So far that is what I would expect. However, if the user closes the
form the dic and all the Objective-C objects are released. I would
expect memory usage to go down to 100M or so but it stays at 423M. I
have made sure that dealloc on the objects is called.
Shouldn't the process return memory to the operation system so that we
see decreased figures in prstat? I am seeing this on Solaris 10. I have
no idea whether this is Solaris or GNustep related or a general memory
management issue under Unix operating systems.
Thanks for you hints!
Andreas
