Hi RVK,
JLD1 never has the problem described, only JLS1 has these errors. I have been developing on JLD1 for more than 2 years, and never once have any of my Lazarus apps shown this error.
Yes, I am working locally with the .exe, but my connection string was specifically for an INET port 3050 connection.
The error displayed in Lazarus is "Unable to write to the connection". In the firebird.log, it lists these as the following:
JLS1 Sat Oct 24 14:29:33 2020
INET/inet_error: read errno = 10053, aux server host = JLS1, address = fe80::3862:88ff:3231:1c98%6/51463
JLS1 Sat Oct 24 14:29:33 2020
INET/inet_error: read errno = 10054, client host = jls1, address = fe80::3862:88ff:3231:1c98%6/51461, user = JOESMITH
JLS1 Sat Oct 24 14:29:33 2020
INET/inet_error: send errno = 10054, server host = JLS1, address = fe80::3862:88ff:3231:1c98%6/3050
Always in groups of 3 as shown. Always the same errors shown.
RUBI (Lazarus .exe) is unusable after one of these happens and must be shut down and restarted. (It sometimes is stuck and will not even respond to a click on the "Close X" top right corner and must be End Task'd) These errors appear on JLS1 using RUBI after anywhere from 1 second, to about 40 seconds of use. On JLD1,(server without the problem) Windows Defender has been shut off for Firebird's .exe, and .fbk and .fdb, but not for RUBI .exe. On JLS1, (server with the problem) Windows Defender virus checker has been shut off for Firebird's .exe, Firebirds' folder, RUBI's .exe.
Difference: Only on JLS1 there are legacy .exe's
running that access a different Firebird database, using Delphi and TIBCConnection and other TIB Query components. On JLD1, those same components are present and in Delphi, but the Delphi apps are not running.
Let me know if you need any more info. I am happy to "help you help me".
