Thank you for your comment .
ID is 1197198 and it can be known from KM03790727 .
A hotfix was provided for DP10.90 linux .
The same issue occurs with DP10.91 , but a hotfix doesn't exist yet .
The customer will raise a new case soon to request it .
When a fix was provided without CR number , I usually don't write the IM ID in Community Tip because it's not visible to customers .
Instead , I write down the ID to Internal field of KM document .
Anyway, I expect that anyone who is interested in the fix can always ask me as you did
