In VOQ based chassis where syncd uses VOQ SAI, if there are large number of front panel ports, SAI takes more than 1 minutes to complete the switch create initialization. Because of this, the switch create request sent by orchagent is not getting response within the default response wait time of 1 minute. So the orchagent declares switch create failure and crashes. The number of ports need to be initialized by SAI depends on number of ports per asic and total number of system ports configured in the system. The total number of system ports in the system in turn depends on number of line cards supported, number of asics per line card and number of ports supported by each asic. Therefore in a fully populated system, which is an often expected scenario, this crashing will happen. To fix this, in orchagent, the syncd response time out is set to 5 minutes for line (voq) card and 10 minutes for supervisor (fabric) card before sending request for switch create and is set back to default wait time after the switch create.

What I did
Fix for syncd response time out for switch create request from orchagent
Why I did it
In VOQ based chassis where syncd uses VOQ SAI, if there are large number of front panel ports, SAI takes more than 1 minutes to complete the switch create initialization. Because of this, the switch create request sent by orchagent is not getting response within the default response wait time of 1 minute. So the orchagent declares switch create failure and crashes.
The number of ports need to be initialized by SAI depends on number of ports per asic and total number of system ports configured in the system. The total number of system ports in the system in turn depends on number of line cards supported, number of asics per line card and number of ports supported by each asic. Therefore in a fully populated system, which is an often expected scenario, this crashing will happen.
To fix this, in orchagent, the syncd response time out is set to 5 minutes for line (voq) card and 10 minutes for supervisor (fabric) card before sending request for switch create and is set back to default wait time after the switch create.
