HHC00936E 0:0E21 CTC: error writing to file E0-69-95-2E-AF-56: No error

Hello group,
 

 I have been getting this HHC00936E message intermittently after a reboot of the host system (Win10-64) for quite a while now, here are some relevant log entries:

 

 ...

 10:12:39.124 00001754 HHC01413I Hercules version 4.3.0.9795-SDL-g287d2d40 (4.3.0.9795)

10:20:46.016 00001754 HHC00007I Previous message from function 'LCS_Write' at ctc_lcs.c(1160)
 ...
 

 The LCS interface then becomes inoperative to the guest operating system and cannot be restarted.
 

 Restarting the guest operating system and hercules itself after getting the error above resolve the issue until the next reboot of the host system.
 

 Any ideas on how to fix this HHC00936E 'No error' error message?
 

 Here is the relevant config information:

 

 0E20-0E21 LCS     -o D:/Hercules/CONFIG/OAT/E20.OAT
 

 Here is the E20.OAT file:
 

 0E20  IP   00  PRI 192.168.2.15
HWADD 00 02:00:15:00:0E:20

 

 Thanks,  Yvan
