I am running Data Services 4.0 SP3 on Windows 2008 R2.
I am executing batch jobs via the web service calls.
For the most part this jobs execute without a problem. The typical run time is between 45 and 60 seconds. However if the input file size is large then the job could take 15 to 20 minutes. All of this is fine.
However over the past week we have experienced a problem on 3 separate occasions.
I know that there is a problem when I start to see jobs queuing in my system that submits the job via the web service calls. I only allow three jobs to be processing at the same time. My program queries the job status through the Get_BatchJob_Status web service call. This system is independent of Data Services. When I log into the management console I can see that there are jobs that are either red with an error, or green, but nothing is being processed -- other than a few lines in the trace log everything is empty.
I can't find any error logs on the system or within the management console for these jobs. I have looked in C:\Program Files (x86)\SAP BusinessObjects\Data Services\log and in C:\Program Files (x86)\SAP BusinessObjects\Data Services\log\JobServer_1 and within the repository subfolder, but there are now error logs for the time that these problems are happening.
I have tried restarting the DataServices service, however that does not enable job to be processed. All jobs still hang.
The only solution that I have found so far is to preform a server restart. However, sometimes that does not work the first time and I am forced to restart yet again.
Therefore it seems to me that something at a lower level, (perhaps Apache?), is crashing and sometimes not able to start even after a reboot. But I am only guessing as I have no evidence as to the cause of the problem.
Does anyone have any ideas of where I can start looking?
Thanks!
