Description

Does anybody else get this when making a new stack from selected particles from an alignment?
... Assembling database insertion command
... Inserting particle information into database
Traceback (most recent call last):

If I revert to myami-3.1, there is no problem because it does the inserts one at a time instead of making one big MySQL insert statement. This only seems to happen for bigger stacks.

Update, Donny changed the MySQL configuration, and I think that fixed it. From Donny:

line 14 in the server configuration file: /etc/my.cnf.d/server.cnf

It was set to 8M and I changed it to
max_allowed_packet = 32M
