We have had an issue where our HANA express instance became unresponsive with high CPU. We decided to reboot and found that after it came back up, our primary taskchain now will not run. When executed, it says aborts with an error message saying "Number of parallel Task Chain runs 2 exceeds limit of 1".
I've googled and looked into what I can but I can't see how to clear this. Presumably there is a process linked to this taskchain which it still thinks is running but I can't see where I can kill/end this process to re-run it?
There doesn't seem to be anything in SAP notes either?
We have a workaround of duplicating the taskchain but this issue has now happened again and blocked the copy. So - while I can carry on duplicating it and hoping it doesn't happen again - I'd prefer to clear it properly!
Any suggestions gratefully received.
