Thanks.
All the obj-browse have "ReadOnly" selected and the obj-save step has Write now and with error.
I am still checking if there can be any lock issue, but i dont think so.
Question is why does it show Caused by stackoverflow.. is there something to do with the memory or something?
Hi ,
I did some research on the stackoverflow error i found plenty around in the existing SR’s , however didn’t find anything with the similar stack trace reported in 6.2 SP2 .
This needs to be looked upon by the product team to have their say .
Please raise a SR with GCS and do mention this PSC thread you already created .
Thanks,
Arun
Hi,
Looking at the exception, I feel that when you are trying to loop the table, it may be running for too long, can you please check how many records are present in the database which we are trying to modify. If possible, can you check what happens with less no. of records. Please share us your observations.
Regards,
Rachit
Hi, The table contains approx. 30k records, so that should not be an issue. The Obj-browse is also well filtered, so that is returning minimal results, so no issues there. Any other things that you think might be affecting? Thanks.
I could see "doWithRequestorLocked" exception. But couldn't predict exact root-cause.
Please share more information about the Activity and the configured obj-browse method.
To isolate the root cause, add the logger(using Log-Message method in activity) to retrieve stack trace after browsing object from the table and again while saving it in another table. It seems to be an issue with locking.Kindly share the full stack trace for further investigation.
