Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Gowtham Thommandra (trgowtham) Assigned to: Nobody/Anonymous (nobody) Summary: walking all available MIBs might cause a memory leak Initial Comment: A ~6MB/day memory leak in snmpd, which over time brings down the system. This can be reproduced when running the following command repeatedly /usr/sfw/bin/snmpwalk -v3 -u root1234 -l authNoPriv -a MD5 -A root1234 127.0.0.1 I am attaching the patch file containing the fix that needs to be integrated. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=312694&aid=2883155&group_id=12694 |

I'm not totally convinced tat the third case (freeing the PDU at the end of the handler) is necessarily correct. Once snmp_async_send has been called, freeing the PDU structure is probably the responsibility of the callback handler. It doesn't feel safe to release things quite so quickly. Hence I'm leaving this tracker item open for the time being. ---------------------------------------------------------------------- Comment By: Dave Shield (dts12) Date: 2009-11-30 14:55 Message: Thanks for the patch! It has been applied to the 5.2.x, 5.3.x and 5.4.x code branches and the main development tree, and will appear in future releases of the Net-SNMP package. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=312694&aid=2883155&group_id=12694 |
