[FB3 CS] Server stops accepting new connections - lock denied
-------------------------------------------------------------
Key: CORE-5813
URL: http://tracker.firebirdsql.org/browse/CORE-5813
Project: Firebird Core
Issue Type: Bug
Components: Engine
Affects Versions: 3.0.3
Environment: Linux 3.10.0-693.21.1.el7.x86_64 SMP x86_64 (CentOS 7),
FB 3.0.3.32900 x64, access via fbclient.dll (both x86 and x64) from Delphi's
FireDAC and Flamerobin
Reporter: John Franck
Classic Server stops accepting new connections, while already active ones
continue to work regularly.
Load conditions seems irrilevant, we had a total of 4 events in less than a
week, two of these during very low load conditions and two in average
conditions.
Error in firebird.log (this is the last event this morning, load conditions at
6 am are extremely low in our environment):
------------------------
sqlserver Thu May 3 06:17:56 2018
Database: /opt/firebird/security3.fdb
page 0, page type 1 lock denied (216)
sqlserver Thu May 3 06:17:57 2018
Database:
page 0, page type 1 lock denied (216)
------------------------
I've also noticed there are other errors in firebird.log, but these seems not
to be related to any connection problems (I've got no reports from users). I
put them here anyway:
------------------------
sqlserver Wed May 2 18:43:50 2018
Database: /opt/firebird/security3.fdb
page 377, page type 3 lock denied (216)
sqlserver Wed May 2 18:43:52 2018
Database: /opt/firebird/security3.fdb
page 377, page type 3 lock denied (216)
sqlserver Wed May 2 18:43:53 2018
Database: /opt/firebird/security3.fdb
page 377, page type 3 lock denied (216)
------------------------
This problem seems to be similar to this one:
http://tracker.firebirdsql.org/browse/CORE-5436 which however affects Firebird
on Windows.
This is a big problem for us, service is going down from time to time and
requires a server restart.
