We have a few databases running on a server and periodically, the server will become unresponsive to web direct, pro and go clients.
This will usually happen during times of moderate activity (less than 10 users most often, mostly using WebD or Go) or when running a server script, this issue never happened under previous versions on FMS14 and was running reliably on 18.104.22.1682 for many months, since upgrading to 22.214.171.1242 or later (including FMS15), the issue occurs daily sometimes multiple times. Rolling back to 126.96.36.1992 resolves the issue.
When the issue occurs, users can still log on via WedDirect, Go or Pro. But they get a blank screen (WebD users get the Filemaker Navigation button at top-left but it is unresponsive and this should be hidden in the open script).
Logs show issues with lock conflicts during a daily backup with 2 database users Admin (); Admin() but I don't have a user account of that name.
The server is as follows: -
2 x Intel 6 Core Xeon E5-2630 v2 @ 2.6 GHz
Perc H710 RAID w/ 4 x 15k RPM 300GB disks in RAID10
Windows 2012R2 Standard
All hardware drivers and recommended or critical windows updates are installed.
Any help would be appreciated.
