I have a FileMaker server 18 installation that’s crashing about once a week. When I look at the event log for the time of the crash. I see client 1 not responding, client 2 not responding etc. until all clients are disconnected. All databases show as open in the server console. From a client PC no open files are listed for the host. If I telnet to the server from a workstation on port 5003 a connection can’t be established. Stopping and starting the database server does not help. Restarting the FileMaker service does not restore operation. The server is still communicating with the network. I can open a web page or browse other computers on the network. Restarting the Windows server restores normal FileMaker operation. My environment is as follows:
Windows Server 16 Standard Edition dedicated FileMaker server.
8 GB memory
80 GB RAID disk drive (40 GB free)
Indexing turned off
No third party backup software running
No AV software running
Windows File Sharing turned off for all folders.
Windows Defender Turned off
IPV6 protocol turned off
What we have tried so far:
We replaced the network switch (after the first crash a few weeks ago).
Tested all databases for corruption.
Compacted all databases
Reinstalled FileMaker Server 18
Any insights would be greatly appreciated
