Hi.

I am using Zabbix Server 6.0.23 with odbc monitoring.
On server Oracle Client 19 installed.

cat /etc/odbcinst.ini
[Oracle 19 ODBC driver]
Description     = Oracle ODBC driver for Oracle 19
Driver          = /usr/lib/oracle/19.12/client64/lib/libsqora.so.19.1
Setup           =
FileUsage       =
CPTimeout       =
CPReuse         =

Periodically, when Oracle database servers are overloaded ODBC pollers on Zabbix stuck. Data from Database monitor stops flowing, in Zabbix server Utilization of ODBC poller metric show overload.
It seems that in some cases the timeout does not work. The problem does not occur often, once а month or two.
Restarting Zabbix server helps.
