Solution
Message 1
For the benefit of other readers.
The crash with call stack above happened very frequently in the customer.
In the OM logs right before the crash there was this error that
suggested the communication between Siebel Web Server and Siebel App
Server was terminated:
SisnTcpIp SisnSockError 1 0 2007-10-22 12:50:25 11712:
[TCPIP-server] send() failed for sd=3768 (err=10054 | An existing
connection was forcibly closed by the remote host (peer).)
Because of the crash other subsequent messages were seen in SCBroker log. But they are just a consequence of the crash:
SBL-SCB-00005: Connection timeout waiting for message.
SBL-SCB-00011: Failed to connect to pipe (SEBL_3_5608) on process 5608.
Further, this was last actions captured by *.fdr file. But again this
was just a consequence and it was not related to the root cause of the
crash:
Communications Client Business Service PushToolbarMessage
Communications Client Business Service PushToolbarMessage
Fire Service Event Communications Client WaitForCmd
Solution:
After disabled SNMP protocol to diminish the retransmission of the TCP packages, this crash was no longer seen.

Symptoms
Customer is facing recent and intermittent unavailability of WfProcMgr
component installed in one server. Customer has noticed one occurrence
this Sunday 02/15 at 10:30 AM and 02/16 3:20 AM. When it occurred they
were able to restart the server. Customer is not able to always restart
the siebel server because the application does not respond in a timely
manner.
Since WfProcMgr seems unavailable for some reason
SISNAPI errors in SRBroker logs were found also as a consequence of this
component being unavailable it seems that records in S_ESCL_REC are
increasing.
The records in S_ESCL_REC seems to be associated to
triggers created for assignment of campaigns. No recent changes were
made on wf policies or configuration.
In the enterprise log and confirmed that WfProcMgr became unavailable.
From the Enterprise logs the related WfProcMgr logs and this analysis resulted in 3 groups of enterprise +wfprocmgr logs:
In WfProcMgr_58975.3.log can also find the error SBL-SMI-00140: Internal: The MT Server has been disabled.
Customer
can see from WfProcMgr_80330.log that the same instance'1-6E1YM0' was
still not able to be resumed even after several hours >
SBL-BPR-00124: Cannot resume process instance '1-6E1YM0'. Verify that it
does exist and has a 'Waiting', 'Suspended' or 'In Error' status.
A3,
B3: For the Workflow Process Manager created by the Siebel Server
Scheduler at 2009-02-16 03:19:36 with task id 80973 and exited at
2009-02-16 03:20:37.
Finally here Customer were able to find the
error SBL-SMI-00062: Internal: No more process (multithreaded server)
slots available in WfProcMgr_80973.log.
Customer checked the
memory limits and found that memory limits are not being reached (or
reached only 20% below the limit) which indicate that the cause does not
seem memory related.
Cause
There were 2 problems associated to this workflow component crash;hang:
1.
Associated to the jobs executed by workflow process SMCC - List Import
is consuming too many threads. At some point max tasks limit is reached
and as a consequence no more threads can be created to continue trying
to process these records. This would explain why we saw the error
SBL-BPR-00124: Cannot resume process instance '1-6E1YM0'.
2. After this problem was solved it seems that a crash was found.
This crash was associated to the workflow process "SMCC Sync PEM Status
- Contact Phone Status" fails.
The error seems to happen
when the method "'SyncPEMStatus" updates a business component field with
a picklist with a value that is not available in this picklist. The
pick lists name is "Response Outcome PickList".
Solution
1. By stopping the instances in loop from the workflow instance view
have helped to free up some threads and avoid the Max Tasks limit to be
reached. This means that this job that is processing List Import
records must be reviewed in order to ensure that it will not keep in
loop and allocating a high number of threads until the limit is reached.
2.
The suggestion here is to ensure that the value being used (by workflow
process "SMCC Sync PEM Status - Contact Phone Status") to update the
field (by the method "'SyncPEMStatus") exists in the picklist associated
to this field ("Response Outcome PickList").

Goal
If eChannelObjMgr_enu PID crashes the server creates one process for eChannelObjMgr_enu + 1 additional process for SrvrSched.
that's when we hit this error "No more process (multithreaded server) slots available".
Can you please explain the cause of this error?
Below is the log snippet:
ServerLog

Solution
After an OM failure new MT Server PID is started and SrvrSched also starts a PID (as a result some more processes are spawned).
The AOM tuning does recommend you to set MaxMTServer=MinMTServers to avoid overhead time for starting the new process.
However the defect CR# 10642132 causes these error messages appear in the log under following scenario:
When
you have MaxMTServer=MinMTServers and OM crash occurs then component
starts a process as it does not have the requisite MinMTServers running.
The siebsrvr (Scheduler) also starts a process.
If the new process that started sees that it has more than MinMtServers, it will exit.
These message do not imply problem in the above case.
Hence
it would help to set MinMTServers to a lower value than MaxMTServers so
that at any given time you have higher than MinMTServers running but
lower than MaxMTServers.
If the issue persists after thatinvistigate the resource availability aspect of the server and the concurrent OM loads.

Symptoms
SBL-SVR-00028, SBL-SMI-00062
We did a reconfigure on our Call Center Object Manager and see that afterwards we get errors in the log
SCCObjMgr_enu 8213 SBL-SMI-00062 Process
exited with error - Internal: No more process (multithreaded server)
slots available
I suspect that we may not have something set correctly to effectively use the reconfigure option.
Solution
In reviewing the log filles the error "SBL-SVR-00028: No more tasks
available for this component" was also found. Both errors are usually
related to the MaxTasks and MaxMTServers values on the server. The
customer was advised to view the document "Tuning AOM Components for CPU
and Memory Utilization" and Technical Note 388 on SupportWeb, these
give details on how to best calculate the values.
The customer
updated the values of MaxTasks and MaxMTServers, as well as
MemoryBasedRecycle and MemoryLimit, and this resolved the issue.
