Random rdesktop freeze and kernel panic

Hi,

We use rdesktop 1.8.3 in a live distribution (LTSP) on thin client.
Some users have randomly a freeze of their rdp session and it's result 
on a kernel panic.

A user has tried for example to modify a PowerPoint from a Windows 
Session on his thin client. The rdesktop program has freezed when the 
user has begin to modify the PowerPoint. The thin client has been rebooted.


This strace was logged with the 1.7.1. For the moment, I haven't log for 
the 1.8.3 version but the problem seem to be the same...

recvmsg(4, 0xbfc73154, 0)               = -1 EAGAIN (Resource 
temporarily unavailable)
select(6, [4 5], [], NULL, {60, 0})     = 1 (in [5], left {59, 999991})
gettimeofday({1427207735, 661807}, NULL) = 0
recv(5, 
"\2\360\200h\0\1\3\353p&\10\0\0\0|Nv\317:c\332M:E\233\257\260\3f|\211\r"..., 
48, 0) = 48
poll([{fd=4, events=POLLIN|POLLOUT}], 1, -1) = 1 ([{fd=4, revents=POLLOUT}])
writev(4, [{"h\0\1\0", 4}, {NULL, 0}, {"", 0}], 3) = 4
recvmsg(4, 0xbfc73154, 0)               = -1 EAGAIN (Resource 
temporarily unavailable)
select(6, [4 5], [], NULL, {60, 0}^CProcess 5167 detached
