I've got a fresh install of SME v5.6 U4, with the following contribs: ClamAV, e-smith-userpanel, SpamAssassin, and ezmlm.
I have added about 2000 users to the system using a batch_users script that I've used for a long time without any trouble. I just yesterday tried to import about 130 more users. After it processed 100, the last 30 users failed. The usernames show up in the server-manager, but none of the home directories were created, I get an error when modifying the user or resetting the password in the server-manager.
The /var/log/messages file shows me that in /etc/e-smith/events/user-create/S15user-create-unix the group fails to be created, but doesn't give any details as to why.
When I try to run the command that fails manually ("/usr/sbin/groupadd -g GID USERNAME") I get the response "Segmentation Fault". I can't find any more details in any of the logs.
I have tried taking out and rearranging the sticks of memory (4 - 512Mb sticks), to no avail.
Any other thoughts?
