To fix a problem, JetBrains technical support team may request a wide range of information about your system or configuration (e.g. logs or CPU snapshots).
Files under 10 MB in size can be attached right into the tracker issue (if you do not want the attachments to be publicly accessible, limit the attachment visibility to jetbrains-team user group only using the Visible to option under the comment field).
You can also send small files (up to 2 MB) via email: firstname.lastname@example.org (or any other support/sales email you are communicating with). Files up to 20 MB can be attached to the support ticket in the online form or later on any step of communication with our technical support engineers. Please do not forget to mention product name, exact product version in the request (along with other information which might help us to faster understand and resolve the problem you are experiencing).
