Increasing File Descriptors on Mac OS X or Other UNIX System
The ability of Integration Server to handle traffic is constrained by the number of file descriptors available to the Integration Server process. On most systems, 64 file descriptors are available to each process by default. If Integration Server is running on a Mac OS X or other UNIX system, Software AG recommends that you increase the number of file descriptors available to the Integration Server process to at least 1024.
Note:
You might have to increase this number depending on the number of files Integration Server needs to have open at one time. It is dangerous to set the rlim_fd_max value higher than 1024 because of limitations with the select function, so if Integration Server requires more file descriptors, set the setrlimit value directly.
