We have seen the same behaviour. The problem was that if you do not have all
your files on the machine you're compling X11R4 on, the Apollo will take ages
checking the dependencies of the include files. For this it will have to get
the timestamp of these files. So it will start swapping and the network
activity will go up significantly and the Apollo will eventually die.

The solution we used was to get rid off the dependencies. Also you might put
all the necessary files on a local disk. This way the Apollo will not use the
network and will not disrupt your other Apollo's.

Also some Apollos have some difficulties with the optimizer. I compiled it on
an Apollo 2500 mith 8Mb memory with all X related files on local disk without
the optimizer and without dependency checking and this worked OK.

Good luck,

Marten
