Time Out Error while execution of messages

Question

Hello All,
Our Env. is XI 3.0 , and this is related to PRD system,
This problem is relating to an Outbound service. This particular message gets executed in some times and in some cases it throws Time out Exception .
This is the following log which is from Audit log of that message :
Audit Log for Message: 2949b051-ae64-11dc-87b9-001560ad9210
Status     Description
Success     RFC adapter received sRFC for Z_UCRM_FM029_RFC_INT_SERASA from CP1/130. Attempting to send message synchronously
Success     Application attempting to send an XI message synchronously using connection AFW.
Success     Trying to put the message into the call queue.
Success     Message successfully put into the queue.
Success     The message was successfully retrieved from the call queue.
Success     The message status set to DLNG.
Error     Returning synchronous error notification to calling application: com.sap.aii.af.ra.ms.api.RecoverableException: Received HTTP response code 500 : Timeout.
Error     Transmitting the message using connection http://xp0ci01:8080/sap/xi/engine?type=entry failed, due to: com.sap.aii.af.ra.ms.api.DeliveryException: Received HTTP response code 500 : Timeout.
Error     The message status set to FAIL.
Error     Returning to application. Exception: com.sap.aii.af.ra.ms.api.DeliveryException: Received HTTP response code 500 : Timeout
Here CP1/130 is the CRM system which is sender in this case , and XP0 is xi production system.
Can any one help me out to fix this issue, and if any parameter value need to be adjusted...?

Hello All,
Thanks for the update,
I have checked the mentioned Blog and the oss notes mentioned in it..
I have compared all the parameters specified in it , and which seems to be fine as per recomended.
HTTP_TIMEOUT   -30000
syncMessageDeliveryTimeoutMsec --300000
xiadapter.inbound.timeout.default -180000
Few points which I am having doubt :
1>
When I login to SMICM of that system , I can find the error content in most areas and no clue about it..
[Thr 1077967200] Wed Dec 26 17:29:19 2007
[Thr 1077967200] *** WARNING => IcmReadFromConn: AppServer context already released [icxxthrio_mt 2452]
[Thr 1077967200] *** ERROR => IcmHandleNetRead(id=7/22059): IcmReadFromConn failed (rc = -1) [icxxthrio_mt 1257]
[Thr 1077967200] *** ERROR => IcmConnRollInWP: AppServer context already released [icxxthr_mt.c 2339]
2>
And when checked in trace file of dev_server0 , i can see some error messages relating to rfc logon load(SMLG) , but I have checked in SMLG and load balancing is defined over there and the status is also green.
Now one small doubt is , any way this error is relating to the existing problem ..

[Thr 1093638496] *** ERROR => JRFC> Error jrfc_lg LgGroup failed(-6) [jrfc_mt.c    707]
[Thr 1093638496] *** ERROR =>       mshost: ashb01wa06pr, msserv: sapmsXP0, r_group: PUBLIC [jrfc_mt.c    708]
3>Is my only few outbound services messages getting failed showing the reason as "Timeout error 500 " due to inconsistency in SMICM .(as outbound services uses ICM services to connect external part)..
4>And the reason for failing only some messages is due to heavy load( at same time many messages are getting executed)  ?
Can any one help me to fix this issue ...
