* Problem: ---------- I am using net-snmp 5.4 version. One of our application sends trap using send_v2trap() function. When ever this function is called I am seeing memory increase in "snmpd" process. Just after send_v2trap function I am calling "snmp_free_varbind" also. The connectivity between our application and snmpd is AgentX.
* Problem isolation: -------------------- To isolate the issue, I used "$NET-SNMP-INSTALL- DIR/agent/mibgroup/examples/notification.c" file to experiment the same. I see the same behaviour. When ever send_v2trap is called I am seeing snmpd is leaking memory. Around 4-8 bytes every time. * More experiments: ------------------- Then I experimented same in Net-SNMP-5.3.0.1 also. Same behaviour. Connected this application and snmpd via tcp,udp,unix based AgentX communication mechanism. The result are same. Then I tried using valgrind for "snmpd" in following way. valgrind --tool=memcheck snmpd -f -Le -Dagentx -xtcp:localhost:3456 * ValGrind result without calling send_v2trap(): ------------------------------------------------ Received TERM or STOP signal... shutting down... ==22760== ==22760== ERROR SUMMARY: 354 errors from 14 contexts (suppressed: 50 from 2) ==22760== malloc/free: in use at exit: 496844 bytes in 14225 blocks. ==22760== malloc/free: 105774 allocs, 91549 frees, 27785880 bytes allocated. ==22760== For a detailed leak analysis, rerun with: --leak-check=yes ==22760== For counts of detected errors, rerun with: -v * ValGrind result with 90 times calling send_v2trap(): ------------------------------------------------------ ==22762== ==22762== ERROR SUMMARY: 3093 errors from 18 contexts (suppressed: 50 from 2) ==22762== malloc/free: in use at exit: 1000010 bytes in 17818 blocks. ==22762== malloc/free: 128827 allocs, 111009 frees, 40674529 bytes allocated. ==22762== For a detailed leak analysis, rerun with: --leak-check=yes ==22762== For counts of detected errors, rerun with: -v >From the above result we can easily make out there is memory leak in snmpd. Can some one help me on the same. -- Regards, -Navaneetham ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
