I've been trying to track down a memory leak in an application and it seems like my problem is within XbaeMatrixAddRows. What I've been doing to track memory usage of a process is through this command:
ps -ek -opid,ppid,etime,time,vsz,args
I have a function/driver that adds one row into a matrix using XbaeMatrixAddRows then deletes that row by calling XbaeMatrixDeleteRows:
XbaeMatrixAddRows(Mw, XbaeMatrixNumRows(Mw), str, NULL, NULL, 1);
XbaeMatrixDeleteRows(Mw, 0, 1);
/* Mw is the matrix, str contains a fixed size string to be displayed in the list */
If I call this function thousands of times, I will see the vsz output (memory usage for the process) steadily increase. I wasn't expecting the memory usage to increase because I assumed that XbaeMatrixDeleteRows deleted the row that was created and XtRealloc wouldn't malloc more memory since the string size did not change.
I ran Insure/Inuse and Valgrind on this driver and both reported no heap growth however the ps command shows an increase in memory usage over time. Anyone have any thoughts? I would really appreciate any help you can provide.
