Error

Too Many Open Files

Resolution

In order to resolve this error we recommend that you set the ulimit on the OS to be unlimited. Each operating system has a different hard limit setup in a configuration file. While running unlimited may not be typical with servers that share applications, in our experience a customer best practice is hosting GoAnywhere MFT on a dedicated server. This is due to the mission critical processes that GoAnywhere is often responsible for performing.

Under Linux, these settings are often in /etc/security/limits.conf

The hard open file limit on Solaris can be set on boot from /etc/system.

set rlim_fd_max = 166384
set rlim_fd_cur = 8192

On OS X, this same data must be set in /etc/sysctl.conf.

kern.maxfilesperproc=166384
kern.maxfiles=8192

For iSeries:

The maximum may be increased by calling the DosSetRelMaxFH API. There is a DosSetRelMaxFH api() explanation and example in the IBM Knowledge Center.
