On a Linux system, you can set the limit of open files and thread processes in the /etc/security/limits.conf file. A minimum of 8192 is recommended for open file descriptors limit and >128K is recommended for the number of active threads. A typical configuration used for SnappyData servers and leads can appear as follows:
snappydata hard nofile 32768 snappydata soft nofile 32768 snappydata hard nproc unlimited snappydata soft nproc 524288 snappydata hard sigpending unlimited snappydata soft sigpending 524288

Recent linux distributions using systemd (like RHEL/CentOS 7, Ubuntu 18.04) require the NOFILE limit to be increased in systemd configuration too. Edit /etc/systemd/system.conf as root, search for #DefaultLimitNOFILE under the [Manager] section. Uncomment and change it to DefaultLimitNOFILE=32768. Reboot for the above changes to be applied. Confirm that the new limits have been applied in a terminal/ssh window with "ulimit -a -S" (soft limits) and "ulimit -a -H" (hard limits).
