Severity: 3-Major

Symptoms

When there are thousands of rows in the virtual_server_stat table and mcpd receives a query for for all virtual server or virtual address statistics, mcpd can take a long time to process the request. There might be thousands of rows if thousands of virtual servers server are configured. There could also be thousands of rows if there are virtual servers configured for source or destination address lists, where those lists contain tens or hundreds of addresses.

Impact

When mcpd is processing a query for virtual server statistics: -- TMSH and GUI access is very slow or non-responsive. -- SNMP requests timeout. -- mcpd CPU usage is high.

Conditions

-- Thousands of virtual_server_stat rows. -- mcpd processes a query_stats request for the virtual_server_stat table.
