Prepare to Install Integration Agent or Integration Server on a Mac OS X or Other UNIX System
The ability of Integration Agent or Integration Server to handle traffic is constrained by the number of file descriptors available to the product’s process. On most systems, 64 file descriptors are available to each process by default. If you are going to install the product on a Mac OS X or other UNIX system, Software AG recommends that you ask your system administrator to increase the number of file descriptors available to the product process to at least 1024.
Important:  
You might have to increase this number depending on the number of files Integration Agent or 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 the product requires more file descriptors, ask the system administrator to set the setrlimit value directly.
