I have compared the source code of features/locks between 3.2.7 and 3.3.1. I find mutex lock is added in various functions, such as get_domain function. Are these changes updated to 3.2.7 branch? From: Anand Avati [mailto:anand.avati@xxxxxxxxx] Can you please verify if this issue exists in the master HEAD? There have been quite a few locking changes/fixes recently and this may be a specific case of those issues.
