## Symptoms

- * When transferring many small sized files through the gateway, download speeds are reduced (0-50KB/s) and the transfer process often freezes.

* The issue goes away after Anti-Virus SMB is unchecked: Go to Security Policies \> Threat Prevention \> Policy \> Custom Policy Tools \> Profiles \> Profile \> Anti-Virus

* DLPU debug (fw_debug dlpu on TDERROR_ALL_ALL=5) shows the following lines:

  `[13645][12 May 12:44:36][RANGE_MNGR] file_range_mngr_init: Max number of open files (1001) for range files has exceeded. Will not handle this file`
