Error

ORA-00600: internal error code, arguments: [729], [408], [space leak], [], [], [], [], [], [], [], [], []
Incident details in: /u01/app/oracle/diag/rdbms/tabsdr/TABS2/incident/incdir_33266/TABS2_ora_5348_i33266.trc

Cause

Memory leak problems generally occur when Oracle is trying to free memory allocated to a process. The memory leak dump is generally discovered during session logoff, when Oracle frees the heaps that are allocated for the user process.

Solution

When a user connects to Oracle, a user process is created and at that time the heap is allocated. Every process will have its own memory heap.

If there are no other errors reported at the same time, this may be a case where the error was a rare occurrence and can be safely ignored. As a rule of thumb, leaks less than 90,000 bytes in size are considered to be of low significance.

In this case the space leak is very very low i.e 408 which can be very safely ignored.
