IChat in Leopard - vcencoder process constantly hangs

I recently did a clean Erase and Install of 10.5 and imported my applications back via Migration Assistant.
Since the upgrade, my chats (so far, all of my chats have been with 10.4 users) become choppy and unresponsive after several minutes. Activity monitor reveals that vcencoder is unresponsive. Occasionally, so is coreaudiod.
I do mention above that my chats have been with 10.4 users, but I don't think that's the issue. When I kill vcencoder in Activity Monitor, the chat can continue smoothly with me still receiving video and audio and the other side receiving only audio (which makes sense because I think vcencoder is the process which encodes my video signal).
Anyone else experiencing this on a similar setup?

Leopard Server's only just (finally) giving us multi-user calendaring... I think PBX/VOIP in OSX server might be a long way off

IChat 4.0 - vcencoder process hangs

Since doing a clean Erase and Install of Leopard onto my iMac G5, the process "vcencoder" hangs a few minutes into my video chats. (This according to activity monitor). This inevitably disrupts the chat a few minutes later (although not right away). Only killing the process ends the disruption, but it turns the chat into audio only in terms of what the other side sees/hears, whereas my side continues to display video and audio.
Any ideas?

"vcencoder" process slowing video chats

During all video chats my Macbook begins to heat up, the fan kicks into gear and friends on the other line tell me my video quality is degraded. My processor seems to be getting overloaded, and I've discovered that the "vcencoder" process is eating up 40-70% of my power, while the "ichat" process itself wants another 50% or so.
Is this normal? Is there any way to not have my machine overloaded like this?
I've tried rebooting and even reinstalling iChat, but to no avail.

Did you use ChatFX or ShowMacster Add-ons in iChat 3 ?
Have you deleted them ?
10.4.10 broke ChatFX and it should have been deleted then.
I take it this never fails with an Error log number ?
Can you check Users/(your account)/Library/Logs/iChatConnectionsErrors and see if you have any since upgrading to Leopard.
If you Open one it will open in Console and drop to the Bottom of the Log.
It is likely to be very long.
The bottom is all the Binary Images info of what was open at the time
It will list at the top of that section what was involved in iChat's start up.
SO at the start of the Binary Images does it mention in the first 5 or 6 lines anything about the Add-Ons I mention ?

VoIP, PBX and iChat in Leopard

We've recently had serious problems with our ISP and BT at my work (in the UK), which has prompted us to consider changing ISPs:
http://bbs.adslguide.org.uk/showthreaded.php?Cat=&Board=whichbusinessisp&Number= 2617948
In the process I thought it would be worth looking into VoIP, but one thing I need to get to the bottom of is PBX when using VoIP. Can anyone offer any advice on potential solutions/alternatives?
What are the chances of iChat in Leopard supporting VoIP to ordinary telephones and some sort of built-in PBX system?
I've had a quick look at Asterix (which is compatible with Gizmo Project) http://en.wikipedia.org/wiki/Asterisk_PBX but it doesn't seem like the easiest software to install/maintain. Does anyone have any experience with it on Mac OS X?
Our hardware currently consists of:
10x Workstations running Mac OS X 10.4.7
1x Server running Mac OS X Server 10.4.5
Our current PBX system is BT's Versatality:

Spinning beach ball with Leopard 10.5 - mach_msg_trap - Hangs

Hi,
since I upgraded to Leopard, my Macbook Pro hangs sometimes. I recorded today such a hang (10-20 minutes, spinning beach ball) with "Spin Control".
It seam to me, that some resources are locked by the OS. Is anybody able to describe what happens?

Process Flow hangs

I'm executing a process flow with several activities.
After each activity I check for status and error out if the activity fails. If the activity succeeds I go on to the next activity.
When I execute a map within the process flow, the process flow executes successfully only if the map is the last activity. The map functions to output data to a file.
The Process Flow hangs if after the execution of the map
a stored procedure is called. The stored procedure dynamically creates a DBLINK and updates a table.
When I cancel the execution of the process flow I see the map has successfully outputted all
records. But why hasn't it gotten to the stored procedure.
Each activity on its own works fine but in combination with each other they hang the process flow.

Mahesh,
I am assuming that RAB stands for Runtime Audit Browser.
The Runtime Audit Browser tells me how many records were
rejected but not which ones and why.
The debugger does not give adequate information in fact it does not issue a "break" where it should.
Are there any tools OWB provides for "catching", or
auditting data that cannot for whatever reason be extracted to a file.
I see that they have a mechanism for capturing problems with data coming from a file into a table. I don't see
where there is an explanation of error handling going from a table into a file.
Thanks!
Marion

Process flow hangs when mapping execution fails

Hi,
Has anyone faced the 'process flow hanging' problem after upgrading to OWB 9.2.0.4? Don't know why this is happening again after the upgrade. The audit browser clearly indicates one of the mappings has failed and workflow tables indicate there was a notification upon failure. The process flow runs several sub process flows each containing 5-6 mappings.
Also, the mapping that failed (due to unique key violations on the target table) executed the post mapping stored procedure although the post mapping run condition was set to 'ON SUCCESS'. Is this the expected behaviour for the post mapping operator when there are database related failures?
Our environment is OWB 9.2.0.4 on AIX 5.2.
Database version is 9.2.0.5. We recently upgraded the database from 9.2.0.4 to 9.2.0.5 and OWB from 9.2.0.2.8 to 9.2.0.4. Process flows are executed using sqlplus.
Thanks,
Chethan

Hi,
I would expect you to have less issues with 9204 as there were some fixes applied. So I have not seen this before.
To get into the mapping a little bit more, is this a row based mapping that is under the tresshold? In any case, if you specify "on success" I would expect it to only work on success... A database related error will also cause it to get an error, so this is interesting as well.
Does the error repeat at any case if there is a failure?

Isight firewire cam not working in iChat on Leopard.

After installing Leopard on my Powerbook G4 867 dvi, my Isight Firewire Cam is not working anymore
in Ichat on Leopard.
Any solutions, it worked fine under Tiger.
Isight firewire cam works fine wirh Skype, Amsn , Photobooth and Quicktime.

Alright. I've done quite a bit of testing now.
My system is (as stated below,) a 12" PowerBook G4, 867 MHz, 640 MB RAM, 40 GB hard drive, Combo drive, AirPort Extreme. It was purchased in Summer 2003, and while the OS has been reloaded, it hasn't been for a long time, and at present, the OS was an install of Jaguar that was upgraded to Panther to Tigard, finally to Leopard.
I was experiencing the issue mentioned. In my case, I use a FireWire miniDV camcorder for video in iChat. It has worked fine in the iChat AV beta in Jaguar, and iChat AV in Panther and Tiger.
Upon upgrading to Leopard, I get the "Slow Network" explanation for why I cannot use video (or hosting multiperson audio, or screen sharing.)
My research shows the following:
This occurs both on the upgraded install, and a fresh install. (To an external hard drive.)
Using Ecamm's PowerBoost allows me to use every option that isn't barred outright by lack of hardware (video effects.) This includes both "Slow Network" issues and "Insufficient CPU" issues (essentially just multiperson video.)
So my guess is that the "Slow Network" is indeed a "bug", and will be fixed by an update from Apple.

Process chain hangs due to locks in SM12

We are currently experiencing issues when executing the process chains. The process chain hangs at one or more DTP loads without executing the following step even though the DTP load is successfully complete (Green). Upon research found that the system locks in SM12 are not released for these DTP loads which is causing the process chain to hang.
Once I delete the lock manually, the process chain continues with the subsequent steps. This is painful during night time loads and hence am wondering if you guyz are aware of a fix for this problem.
FYI, we our system is BI 7.0 and SP 13. Any leads towards the solution are highly appreciated. Thanks!

hi Chetan,
Please enlight me, with your suggestion here you are asking to increase the BGD processes for that particular process chain or for system (SID) as whole?
Please help to understand better.
Thanks in advance

Process flow hangs in state "bussy"

Hi,
We are encountering what seems to be a "random" problem when runing process flows. In about 1 out of 4 runs the flow "hangs" with status "busy"
The technical specs are as follows:
OWB 9.2.0.2.8 on WIN2K Server SP4.
There are two runtime repositories on two different WIN2K database servers (Oracle 9.2.0.4 EE)
The symptoms are as follows:
- We have more than 10 process flows containing from 15 to 60 processes. The problem is not related any single process flow, and occurs on both our target servers.
- The process flows runs OK in approximately 3 out of four runs.
- When the process flows "hangs", one or more of the processes in the process flow also hangs in the "busy" state. The hanging process can be a mapping or an external process
- The processes that have status "busy" have actually finished. They have a completion time set, and in the case where the process sends mail, the mail has been received. In the case of mappings I have verified that the mapping has completed, and that the session performing mapping has terminated.

Session 17 is the runtime service, and these two locks are present under normal operation. Session 48 is the Sqlplus session runing the execution template, and session 67 is (i think) the session that is causing the problem.
- The advanced queue WB_RT_NOTIFY_QUEUE tab shows "Number in state ready" equal to the number of processes still in the state "busy" i the process flow.
- When the runtime service is stoped (using the stop_service.sql) The locking sessions disappears.
- When the service is restarted, the processes change status to "bussy recovery" There is now a RPE-01008 and a RPE-01009 message in the "errors" section for the mapping.
- After the failed recovery, everything looks normal, except that there are now twice the number of messages in state READY on the WB_RT_NOTIFICATION_QUEUE. The only way I have found to get rid of these is to delete them from the queue table.
Is this a known problem? We are about to go live in a few weeks, and this could be a serious show stopper if we can't rely on the daily process flows to run as expected.
I could log a TAR on this, but I suspect support would ask for a test case, and Im going to have a hard time providing it for them in this case.

Jean-Pierre,
Thanks for the update. I was afraid this was going to be one of those "hard to pinpoint" issues...
When the problems occurs the Worflow Monitor always shows the task status as "Notified".
The "Main routine" is no longer executing. The session that was executing the mapping has disconnected, and the mapping has completed successfully. (I have verified this by checking the rows in the target tables). Also, the problem is not restricted to mappings. Sometimes it happens to "mail notifications", and in these cases the mail message is received as expected.
It looks to me like there is some kind of synchronization problem between AQ and the controlling process (the runtime access user session) that can arise under a given condition (which I unfortunately have not been able to determine what is). As far as I can tell, the process executing the mapping completes and puts the message that it has completed on the Notify_Queue (hence the messages in stat "Ready" on the queue), but for some reason the process waiting to read the message fails to do so.
As for a test case, I have recently sent an export of our design repository to Igor Machin. Is it possible for you to have a look at that? As I mentioned in the first post, our Process Flows are fairly complex. Some of the flows are executing 50+ mappings in parallel.

BPEL Processes are Hanging.......

Hi,
I am using BPEL 10.1.2.0.2 version. The logic am implementing in BPEL process is a frontend application will invoke BPEL process.BPEL will take some inputs from frontend and invokes a procedure in database using DbAdapter.BPEL will pull the output of the procedure and will pass the same to Frontend.
The logic being implemented in procedures is select and update depends on the requirement.
We completed our development and moved to UAT and everything is running fine.From past one week we are facing a problem that BPEL processes are hanging when they are invoked both from BPEL console and Frontend. The process neither displaying any output nor throwing any exception.
After bouncing the BPEL servers everything is coming to normal.I didn't found any error log in both domain.log and OraBPEL~OC4j_BPEL~default_island.log files.
Our BPEL Environment has 2 BPEL Mid Tiers connected via a loadbalancer
whether it could be related to cache size or datasource connections ????
Please suggest what could be the problem...........
Thanks
Chandra

Check the timeouts on the firewalls. Also look at Dead Connection Detection (DCD) on the database server. You will need to turn on your DCD to keep your JDBC connections alive.

Buddy List window does not appear when starting iChat in Leopard

In Tiger when I started the iChat application, the Buddy List window always appeared immediately. In Leopard, it does not appear and I must choose Window from the menu bar and then select AIM Buddy List. Does anyone know how to correct this so the Buddy List window appears automatically when I start iChat in Leopard?

Try to create a new profile as a test to check if your current profile is causing the problems.
See "Creating a profile":
*https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
*http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.

Are you using any VST plug-ins or audio units? Then check, if they are still compatible. You may need to uninstall them.
