connection-closed

I set up a PPTP server for my company. However, every time I have another computer connected to this server (i.e. our backup server) and a lot of data gets transferred, the connection to this computer closes.

In the syslog on the PPTP server I find this message:

Apr 22 12:44:34 komola-chase pptpd[2581]: CTRL: Reaping child PPP[2583]
Apr 22 12:44:34 komola-chase pppd[2583]: MPPE disabled
Apr 22 12:44:34 komola-chase pppd[2583]: Connection terminated.
Apr 22 12:44:34 komola-chase pppd[2583]: Exit.
Apr 22 12:44:34 komola-chase pptpd[2581]: CTRL: Client 192.168.0.11 control connection finished
Apr 22 12:55:11 komola-chase pptpd[2674]: GRE: xmit failed from decaps_hdlc: No buffer space available
Apr 22 12:55:11 komola-chase pptpd[2674]: CTRL: PTY read or GRE write failed (pty,gre)=(6,7)
Apr 22 12:55:11 komola-chase pppd[2675]: Modem hangup
Apr 22 12:55:11 komola-chase pppd[2675]: Connect time 23.0 minutes.

Hopefully you can help me as to what is wrong. As far as I can tell, there is no compression enabled on the PPTP server (npbsdcomp option).

Thank you!
