Error: Session Timeout During Ascp Transfers
If you attempt an Ascp transfer over a network with high latency or to/from storage with slow read/write, you might receive a timeout error message. You can increase the timeout to allow your transfers to complete.
Node API Transfers of Many Small Files Fails
Ascp transfers that are started through the Node API or Watch Folders to or from servers that have Unix-like OS can fail when transferring many (millions) of small files because the Redis database exceeds available number of file descriptors.
Logs Overwritten Before Transfer Completes
The logs of long transfers of many (millions) of files can be overwritten before the session completes, potentially deleting useful troubleshooting information if an error or failure occurs. To avoid this problem, set the log size to a larger value than the default of 10 MB. For information on other logging configuration options, see Server Logging Configuration for Ascp and Ascp4.
Disabling SELinux
SELinux (Security-Enhanced Linux), an access-control implementation, can prevent web UI access.
