SP question -- saving POST data

[Steven Carmody]

Hi,

We seem to be losing POST data if the user is sent to the IDP when the 
POST arrives at the SP (its an apache/linux host).

We've followed the suggestions here:

https://wiki.shibboleth.net/confluence/display/SHIB2/NativeSPTroubleshootingCommonErrors#NativeSPTroubleshootingCommonErrors-HTTPPOSTformdataislostwhenShibbolethsessionexpiredordoesnotexistyet

but aren't getting the expected good result.

Looking at shibd.log, I see this line before the user is sent to the IDP:

2013-10-16 12:40:18 DEBUG XMLTooling.StorageService [13]: inserted 
record (c40d26763653a4eef9fe0c8e2bcdaee948844c77) in context (PostData) 
with expiration (1381942218)

and these lines after the user is returned from the IDP (but before the 
Assertion is processed):

2013-10-16 12:40:30 DEBUG XMLTooling.StorageService [12]: deleted record 
(c40d26763653a4eef9fe0c8e2bcdaee948844c77) in context (PostData)

2013-10-16 12:40:30 DEBUG XMLTooling.StorageService [12]: deleted record 
(e60877d5ea05b60cfbdf459d2e78b73c1a87a48d) in context (RelayState)

What should I be looking for in the log files ?
