It seems that since the last upgrade to 11.1.2, opt/SecureSpan/Gateway/node/default/var/attachments is filling up. It's now so full that there is no free space left. Of course, we can increase the disk size, but is there another way to automatically remove the amount of files? This should be possible after successful sending.
11.1.2
The /opt/SecureSpan/Gateway/node/default/var/attachments directory is used to temporarily cache large SOAP/MIME attachments and message parts to disk during message processing when they exceed a configurable memory threshold, so raising the attachment.diskThreshold from the current 10485760 to something like 25 - 50 mb will reduce the amount of files which are created , so the FS is filled up less fast and that should solve the issue .
