Hi,
I'm using net-snmp 5.4 on Linux 2.6 kernel (powerpc platform) and it was working fine.
Recently I added the disman/event-mib to the build options to make the snmp agent fire Traps on events of linkUp & linkDown.
linkUp & linkDown traps are working fine, but I'm facing an issue while doing a snmpwalk.

snmpwalk is working fine till I see the output, mteEventNotificationObjects."snmpd.conf".'linkUpTrap' = STRING: _ElinkUpTrap

[root@praseed mibbrowser]# snmpwalk -Os -c public -v 2c 172.21.20.220
sysDescr.0 = STRING: Solectek WiMAX
sysObjectID.0 = OID: netSnmpAgentOIDs.10
sysUpTimeInstance = Timeticks: (43637) 0:07:16.37
"
" (continues.....)
"
mteEventNotificationObjectsOwner."_snmpd".'_mteTriggerFired' = STRING: _snmpd
mteEventNotificationObjectsOwner."_snmpd".'_mteTriggerRising' = STRING: _snmpd
mteEventNotificationObjectsOwner."snmpd.conf".'linkDownTrap' = STRING: snmpd.conf
mteEventNotificationObjectsOwner."snmpd.conf".'linkUpTrap' = STRING: snmpd.conf
mteEventNotificationObjects."_snmpd".'_linkDown' = STRING: _linkUpDown
mteEventNotificationObjects."_snmpd".'_linkUp' = STRING: _linkUpDown
mteEventNotificationObjects."_snmpd".'_mteTriggerFailure' = STRING: _triggerFail
mteEventNotificationObjects."_snmpd".'_mteTriggerFalling' = STRING: _triggerFire
mteEventNotificationObjects."_snmpd".'_mteTriggerFired' = STRING: _triggerFire
mteEventNotificationObjects."_snmpd".'_mteTriggerRising' = STRING: _triggerFire
mteEventNotificationObjects."snmpd.conf".'linkDownTrap' = STRING: _ElinkDownTrap
mteEventNotificationObjects."snmpd.conf".'linkUpTrap' = STRING: _ElinkUpTrap

From this point onwards agent is not responding to snmpwalk.
and I received  
Timeout: No Response from 172.21.20.220
Then onwards agent is not responding anymore to snmpwalk, till snmpd is restarted.

My snmpd.conf looks like 

group   notConfigGroup v1           notConfigUser
group   notConfigGroup v2c           notConfigUser
view systemview    included  .1
access  notConfigGroup ""      any       noauth    exact  systemview systemview

sysDescr       Solectek WiMAX
syslocation    Unknown (edit /etc/snmp/snmpd.conf)

Any hints on what could be wrong? 
How do I fix this ? 

Thanks & Regards
