The method CreateAttachment on Soap Web Services is failing with a timeout, the stdlog shows the following errors:
domsrvr 3900 ERROR domdict.c 1898 No response to trigger attmnt_init (3 time) after 120 seconds; waiting another 240 seconds
slump_nxd 5372 ERROR list.c 2638 Process 0|kt_daemon is still unknown after 900 seconds; cancelling verification and discarding 2 messages
The "kt_daemon" process did not started properly after the Service Desk service was restarted, this results in a failure to create a new attachment object resulting in hang or timeout in the GUI and the error messages referenced previously.
There are two possibilities to solve this situation:
Option 1: Kill the existing kt_daemon process using the task manager, the process should restart automatically and the stdlog should record a message like the following if successful:
kt_daemon 9152 SIGNIFICANT KTDaemon.c 1259 KT daemon ready for action!
Once the record is in the stdlog the attachments should work properly.
Option 2: Restart the Service Desk service.
