Since updating a number of packages after the last Virtualmin update I've noticed repeated segmentation faults on the system. At the same time running processes have increased over 30% and memory close to 300%.
Apache was restarted at one point. As soon as it came online all of the numbers appeared normal yet within 30 minutes they started to climb to the higher-than-normal levels.
I've wondered if perhaps this is related to the post at http://www.virtualmin.com/node/9697 and if the patched libmysqlclient1off mentioned would work. Not being certain, I didn't want to go and install the patch.
