Description: Running "Create bridge" in tibemsadin fails when the selector exceeds a certain length limit. You may notice errors such as "invalid command" or the command is truncated with the error "Error: Invalid bridge specifications: Invalid selector".
Symptoms:
Cause: The error is due to the max length for exec/command line arguments set in kernel parameter. For example, on Linux it is set by ARG_MAX (i.e., _POSIX_ARG_MAX 4096). On newer versions of the Linux kernel, the value can be found from the command "getconf ARG_MAX".
Issue/Introduction
String length limit for selector.
Resolution
Increase the limit in the kernel parameter or try to run the command by script.
1). Include the "create bridge" command in a file (i.e., admin.txt).
