Bunyamin,
I think you better check the following doc. from metalink...

START ********************* Doc ID: Note:31056.1 Type: REFERENCE Status: PUBLISHED Content Type: TEXT/PLAIN Creation Date: 31-DEC-1996 Last Revision Date: 20-MAR-2002

Note: For additional ORA-600 related information please read [NOTE:146580.1]

PURPOSE:
  This article discusses the internal error "ORA-600 [729]", what
  it means and possible actions. The information here is only applicable
  to the versions listed and is provided only for guidance.

ERROR:
ORA-600 [729][a][b][c][d][e]

VERSIONS:
versions 7.X to 8.X

DESCRIPTION: A space leak has been detected in the User Global Area (UGA).

There is NO data corruption as a result of this error.

It is an internal memory housekeeping problem.

ARGUMENTS:
Arg [a] This is the number of bytes leaked

FUNCTIONALITY:
  MEMORY COMPONENT IMPACT:
  PROCESS FAILURE - But only during logoff so impact is minimal.
  NON CORRUPTIVE - No underlying data corruption.

SUGGESTIONS: Event 10262 can be set to safely ignore small memory leaks.

Set the following in init.ora for example to disable space
leaks less than 4000 bytes:

event = "10262 trace name context forever, level 4000"

and stop and restart the database.

Repeated errors or large memory leaks can be diagnosed further by
sending the alert.log and trace files to Oracle support.

Known Issues:

Bug 2177050: ORA-600 [729] after application of the 8.1.7.3 patchset

The resulting trace file will include a memory dump which

shows unfreed memory chunks with the tags "define var info"

and/or "oactoid info".
Workaround: Set EVENT 10262 with a LEVEL greater than the reported

               leak. A value of 100Kb (102400) is a reasonable limit.
  Fixed in 8.1.7.4 and 9.X releases. One-off patches are available for
  most platforms.
