We are using RT 4.4.0 and appear to be having problems attaching files over some size around 100k. If we try to send an email with a larger attachment, the mail message just drops on the floor. If we try to attach a file through the web interface, the icon has an X over it and an error message appears when the mouse hovers over it, plus the attachment is dropped if we try to save the edit.
Looking in the log I don’t see any messages being generated in either case. I do see messages generated when a file is successfully attached though. Our current attachment size settings should allow larger files than ~100k.
Set($MaxAttachmentSize, 10485760); # 10MB
Set($TruncateLongAttachments, “true”);
I’m not sure what else to look at to determine what’s happening or where things are failing. Have I somehow mis-set the config, or could this be a bug in 4.4.0?

Hi,
This is probably a issue with your web server configuration, you don’t
mention what
you are using.
Researching the following may help:
Apache2 - LimitRequestBody
Nginx - client_max_body_size
Best Regards

From the RT Wiki:
If you are using MYSQL, it also has a limit.
for mysqld < 4.0.2 syntax under mysqld is:
set-variable = max_allowed_packet=10M
for mysqld > 4.0.2 syntax under mysqld is:
max_allowed_packet=10M

Martin,
I poked around at the MySQL database thinking we might have a limit there, but it didn’t occur to me to check the web server. We are using Apache 2.4.6 (CentOS).
Turns out the problem was a combination of limits in MySQL, Apache/FCGI, & RT. Once I got them all set properly, adding attachments up to our chosen limit it working. Thanks for the help Martin.
