Hi,
could you please clarify a bit? Are you talking about using a shared drive or clipboard file copy? As for FreeRDP_VirtualChannelWriteEx, you need to listen for CHANNEL_EVENT_WRITE_COMPLETE and free any buffer supplied before there. (see any of the channels like clipboard using that) regards Armin On 31.08.20 23:09, Jonatan Volkov via FreeRDP-devel wrote: > Hi all, > > I am trying to hunt down an issue where during an RDP session via Apache > Gaucamole, copying a file from a shared directory/drive to any location on > the RDP server reserves memory that never gets freed.
