A configuration containing a number of nested objects takes a long time to list or save. For example, the tmsh listing time for a ~2 MB config can exceed 30 seconds.
When commands take longer than 30 seconds to complete, iControlREST times out.
Following is an example of nested objects in a config. If the config contains thousands of such virtual servers, it might take longer than 30 seconds to run either of the following commands: -- tmsh list ltm virtual. -- tmsh save config. ltm virtual vs { destination 10.10.10.10:http ip-protocol tcp mask 255.255.255.255 profiles { ::: nested object http { } http_security { } tcp { } } source 0.0.0.0/0 translate-address enabled translate-port enabled vs-index 26 } .
None.
A configuration containing a number of nested objects no longer takes a long time to list or save, so iControlREST no longer times out. Note: You might still encounter this issue in configurations that have greater than ~6000 nested objects, which is the largest number tested.
