Unterstanding syslog messages from our wlc

Question

Hello,
we use two wlc 4402 (4.1.181.0) and several leightweight accesspoints (AIR-AP1010-E-K9 and AIR-AP1030-E-K9 ) connected to them.
On our syslog server we get a lot of messages from the two wlc, and there are 3 message types which I am a little bit afraid of.
1. ca. 10 times per hour we get the message
apf_80211.c:4792 APF-6-NO_CONFIG_CHANGES: Not saving 'apf.cfg' - no config changes."
Cisco system message guide:
Error Message %APF-6-NO_CONFIG_CHANGES: Not saving '[chars]' - no config changes.
Explanation Not saving - no config changes.
Recommended Action No action is required.
Does anybody know why we get this messages and if it's possibly to suppress them?
2. Intermittently (several times a day) we get the following message types:
a) [ERROR] spam_l2.c 723: Max retransmissions reached on AP 00:0B:85:56:63:40 (CONFIGURE_COMMAND^M , 2)"
b) [ERROR] spam_tmr.c 569: Did not receive hearbeat reply from AP 00:0b:85:56:ae:40"
The MAC address is not every time the same but one of our accesspoints.
On our network management system we get the following trap messages with nearly exactly the same timestamp:
14.01.2008 04:21:56 CET
AP ''00.0b.85.56.63.40'', interface ''0x1'' is down.
When Airespace AP's interface operation status goes down this trap will be sent.
bsnAPDot3MacAddress = 00.0b.85.56.63.40
bsnAPIfSlotId = 0x1
14.01.2008 04:21:56 CET
AP disassociated from Switch.
When an Airespace AP disassociates from a Airespace Switch, the AP disassociated notification will be sent with the dot3 MAC address of the Airespace AP. This will notify the management system to remove Airespace AP from this Airespace Switch.
bsnAPMacAddrTrapVariable =
14.01.2008 04:22:25 CET
AP associated with Switch.
When an Airespace AP Associates to a Airespace Switch, the AP associated notification will be sent with the dot3 MAC address of the Airespace AP. This will help the management system to discover the Airespace AP and add it to system.
bsnAPMacAddrTrapVariable =
bsnAPPortNumberTrapVariable = 1
Cisco system message guide:
a) Error Message %LWAPP-3-TX_ERR3: Max retransmissions for LWAPP control message reached on AP [hex]:[hex]:[hex]:[hex]:[hex]:[hex] for [chars] (number of pending messages is [dec])
Explanation Maximum number of times an LWAPP control packet is transmitted before declaring the AP dead has been reached for this AP. The AP may not be on the network, or might have rebooted.
Recommended Action Check if the AP has rebooted or if it has been removed from the network, or if there are connectivity issues between the AP and the controller.
b) Error Message %LWAPP-3-ECHO_ERR: Did not receive heartbeat reply; AP: [hex]:[hex]:[hex]:[hex]:[hex]:[hex]
Explanation Controller did not get a response for the AP heartbeat message. There may be connectivity issues between the AP and the controller.
Recommended Action Check if the AP has rebooted or if it has been removed from the network, or if there are connectivity issues between the AP and the controller.
Because we don't see any network problems I'm wondering why the connection is lost.
Does anybody have an idea, perhaps CSCsh13928 (http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCsh13928, but we don't have much traffic on the wlans) ?
Is there any possibility to remotely check if the accesspoint rebooted?
If you need further information please give me a short feedback.
Many thanks in advance,
Thorsten Steffen

Thanks for the help.
I have set up to send email and syslog messages from the RME applications. LMS server immediately started to send messages to the email server but syslog messages are not forwarded to the syslog server. Everything was done according to your instructions except that the name of the first script (syslog_forward.pl) is made consistent with what the second script (.bat) refer to (forward1.pl). What's the problem?  Do RME sends the standard syslog messages via UDP port 514?
Sincerely.
