foreground it can send disman traps, but when snmpd run with -p flag it can not
send disman traps:

Thanks in advance for any help,
Iusse 2455:
I've found an issue with Disman traps.
The OS is Debian 7.0
NET-SNMP version: 5.4.3
The relevant section of the config file is:
________________________________
trap2sink hostname.mydomain.com mycommunity
trapcommunity mycommunity
includeAllDisks 10%
load 50 25 15
createUser internal MD5 "mypassword"
iquerySecName internal
agentSecName internal
rouser internal
defaultMonitors yes

Problem:
The snmpd process sends Disman traps when in foreground mode, but not in daemon
mode.
How to reproduce:
Create a dummy filesystem and fill it up:
df -h
...
/dev/mapper/sys-traptest 7.8M 7.8M 0 100% /trap
Start the daemon:
/etc/init.d/snmpd start
The process is running like this:
snmp 20370 1 0 16:00 ? 00:00:00 /usr/sbin/snmpd -LS6d -Lf /dev/null -u snmp -g
snmp -I -smux -p /var/run/snmpd.pid
Check the status of dskTable:
snmpwalk -v2c -c mycommunity localhost dskTable
(relevant lines shown only)
UCD-SNMP-MIB::dskPercent.13 = INTEGER: 100
UCD-SNMP-MIB::dskErrorFlag.13 = INTEGER: error(1)
UCD-SNMP-MIB::dskErrorMsg.13 = STRING: /trap: less than 10% free (= 100%)
ColdStart trap is received in monitoring station:
Apr 22 15:42:38 hostname snmptrapd[36680]: <UNKNOWN> [UDP:
[192.168.126.164]:35505->[0.0.0.0]:0]: Trap , .1.3.6.1.2.1.1.3.0 = Timeticks:
(4) 0:00:00.04, .1.3.6.1.6.3.1.1.4.1.0 = OID: .1.3.6.1.6.3.1.1.5.1,
.1.3.6.1.6.3.1.1.4.3.0 = OID: .1.3.6.1.4.1.8072.3.2.10
Wait at least 10 minutes, but Disman trap is not received.
Stop the daemon, and run in foreground:
$ snmpd -f
Disman trap is immediately received in monitoring station:
Apr 22 15:43:51 hostname snmptrapd[36680]: <UNKNOWN> [UDP:
