Symptoms
Anonymous User Session Pool of the Siebel Inbound Web Services intgeration approach may not recover after Siebel EAI OM Server Component restart.
The scenario of typical occurrence is following:
(1) An external Application performs Siebel Inbound Web Service call using the approach which is using the Anonymous Session Pool. For example it could be a WS-Security headers usage in SOAP call to the "/eai_anon_enu" URL or a solution outlined in the <Note 601681.1> " How to create a totally anonymous web service in Siebel?" document..
(2) The call is successfully executed by the Siebel EAI Object Manager (OM) Component task and the Anonymous Session pool is filled by one running session, ready to accept next calls coming.
(3) The Siebel EAI OM Component gets temporary unavailable (Siebel Component restarted or the entire Siebel Server restart), while the Siebel Web Server (that hosts the Siebel Web Server Extension - SWSE module) continues to run and keep the Anonymous Session pool untouched.
Typical detailed traces in the SWSE log file could look like below, when the SWSE detects outage of the EAI OM (shutdown command):
(Note: The EAI OM Siebel session taken into Anonymous Session Pool is: !5.fc0)
SisnapiLayerLog Error 1 ... [SISNAPI] Async Thread: connection (0x24c88c0), error (1180671) while reading message

SisnapiLayerLog Trace 3 ... [SISNAPI]: releasing connection (0x24c88c0), refCount = 0
...."
(4) The external application performes the next SOAP call and this call fails with the component outage, because the the SWSE can not access the EAI OM sesison context using the information obtained frm the Anonymous Session pool.
The session added to the pool by SWSE module does not point anymore to the actual EAI OM session context, because the accordant component task has been stopped, at the EAI OM component outage.
Typical detailed traces in the SWSE log file outline the connection issue like below:
(Note: The EAI OM Siebel session taken for use from the Anonymous Session Pool is: !5.fc0 - same as in step before)

(5) The external application receives the HTTP 500 error and retries the SOAP Call again.
This time the could could go, if the Anonymous connection pool contained no other sessions.
Otherwise (which is possible during the massive SOAP calls cases) the error remains persistent.
Typical detailed traces in the SWSE log file outline the connection issue like below:

ProcessPluginRequest ProcessPluginRequestError 1 ... [SWSE] Could not get an anon session...PROBLEM
