07/11 12:04:20.82 <SERVERNAME> slump_nxd 3540 ERROR server.c 3744 Unable to handle fast-channel request from 21433|pdmweb:CASMAPP#4ec0e9e8:1648a1528d8:-7fff|PDMWEB to 21433|web:local|slump_cbf; reason: Process web:local has not enabled fastchannel yet
Environment:
SDM 14.1.X
SDM 17.0.X
Cause:
issue is related to multiple NIC cards on server and there was a Timed out attempting to connect fast channel to web:local on the appserver.
The connection cannot reach the slump because is not piking the correct NIC associated to SDM.
Resolution:

Workaround 1:

Configure Priority to NIC that has the SDM server ip configured.


workaround 2:
- On each server, open the NX.ENV file.
- Locate the following lines:
# Uncomment this to turn off Fast Channel
! NX_NOFASTCHAN=1
- Remove the leading exclamation point and space in front of NX_NOFASTCHAN. The line should now look like the following:
NX_NOFASTCHAN=1
- Saved changes and restarted server.
Making this modification will disable Fast Channel communication entirely, which will also remove those error entries from logs.
After these changesĀ 

Restart Servers services in this order:

Start SDM-BG server
Start SDM-Stby server
Start SDM-APP servers for webservices
