Hi, I am testing federated gateways asynchronization with one region and two zones. After several files synchronized completed, I found some error messages was appeared in the log file. It told me that 'Too many open files' when connected to secondary zone. I have modified the parameters of system files: (1) at /etc/sysctl.conf add: fs.file-max=131072 and then 'sudo sysctl -p' (2) at /usr/include/linux/limits.h change: NR_OPEN = 65536 (3) at /etc/security/limits.conf add: * soft nofile 65535 * hard nofile 65535 But these seem not work. Any help would be much appreciated. ----------------------------------------------------- Wed, 11 Nov 2015 09:37:26 GMT /admin/replica_log 2015-11-11 17:37:30,220 14491 [boto][DEBUG ] Signature: AWS west_access_key:SnkgYfieKNQzQwK9Iwy0B9/YxKs= 2015-11-11 17:37:30,220 14491 [boto][DEBUG ] encountered error exception, reconnecting 2015-11-11 17:37:30,220 14491 [boto][DEBUG ] establishing HTTP connection: kwargs={'port': 80, 'timeout': 70} 2015-11-11 17:37:35,331 14491 [radosgw_agent.sync][WARNING] error preparing for sync, will retry.
