thanks for your suggestion, but there are no other processes, only those belonging to the operating system. Using ps, I can calculate that they are in the maximum using about 200 MBytes (and they really do so after rebooting), but the machine has 1 Gigybyte of RAM and free tells me that nearly no memory is left (there is also nearly no memory cached and buffered). I also tried ipcs to find out if there is any shared memory, but it isn't. For that reason, the only one who is able to allocate memory seems to be the kernel, but as you already stated, it seems quite strange that the problem has been seen on several (old and new) kernels. Any more ideas? Thanks in advance, Andreas
